Regole di gioco

Coup è un gioco di carte progettato per 2-6 giocatori, che giocheremo con due. Consiste in un tesoro di monete (infinito per i nostri scopi) e un mazzo di 15 carte, contenente 3 ciascuno dei seguenti tipi: Ambasciatore, Assassino, Capitano, Contessa, Duca. All'inizio del gioco, a ogni giocatore viene data una moneta e distribuite due carte a caso, che mantengono segrete fino al momento necessario. L'oggetto deve essere l'ultimo giocatore con le carte in mano.

Nel loro turno, un giocatore può effettuare una delle seguenti azioni indipendentemente dalle proprie carte:

• Entrate: prendi 1 moneta dal tesoro. Non bloccabile e insindacabile.
• Aiuti esteri: prendi 2 monete dal tesoro. Può essere bloccato da un giocatore con un Duca. Insindacabile.
• Coup: Rimuovi dal gioco una carta di un avversario a tua scelta. Costa 7 monete. La vittima può scegliere quale carta scartare. Se un giocatore ha 10 o più monete all'inizio del proprio turno, deve Coup. Non bloccabile e insindacabile.

A seconda delle loro carte, i giocatori possono anche effettuare una delle seguenti azioni come loro turno:

• Scambio: un giocatore con un Ambasciatore può prendere due carte dal mazzo. Quindi possono scegliere tra la loro mano e le carte pescate quante carte originariamente possedevano. (Cioè, se avessero una sola carta, potrebbero scambiarla con una delle carte pescate o tenerla, e se avessero due carte, potranno scegliere una qualsiasi delle quattro carte.) Le due carte indesiderate vengono rimesse nel mazzo . Non bloccabile, ma sfidabile.
• Assassinare: un giocatore con un Assassino può spendere 3 monete per rimuovere la carta di un avversario dal gioco. La vittima può scegliere quale carta scartare. Può essere bloccato da un giocatore con una Contessa, nel qual caso le monete non vengono restituite. Sfidabile, nel qual caso le monete vengono restituite.
• Ruba: un giocatore con un Capitano può prendere due monete dal proprio avversario. Se l'avversario ha una moneta, prenderà quella moneta. Se l'avversario ha zero monete, non può rubare. Può essere bloccato da un giocatore con un ambasciatore o un capitano. Impugnabile.
• Imposta: un giocatore con un Duca può prendere 3 monete dal tesoro. Non bloccabile, ma sfidabile.

La parte difficile di Coup è che i giocatori possono mentire su quali carte hanno! Non è necessario disporre di una carta per tentare di eseguire l'azione o il blocco ad essa associati.

Quando un giocatore esegue un'azione di una carta, qualsiasi avversario (anche uno che non è danneggiato da quell'azione) può sfidare l'attore e dire di non credere di avere la carta per quell'azione. Se lo sfidante ha ragione, l'azione viene annullata e l'attore deve scartare una carta a sua scelta (riprendendo le monete che ha speso, se applicabile). Altrimenti, l'azione viene intrapresa, l'attore restituisce al mazzo la carta sulla quale erano stati sfidati e ne pesca una nuova, e lo sfidante deve scartare una delle sue carte. I giocatori devono essere sinceri su quali carte possiedono quando vengono sfidati.

Le carte eliminate dal gioco con Assassinato, Colpo e sfide perse non vengono restituite al mazzo, ma le carte rivelate come parte di una sfida vinta vengono restituite al mazzo.

I blocchi possono essere sfidati proprio come le azioni. Ad esempio, se il giocatore A richiede un aiuto straniero e il giocatore B dice "Ho un duca e blocco il tuo aiuto straniero", A potrebbe dire "Non credo che tu abbia un duca". Se tale affermazione è corretta, B perde una carta per essere catturato in una bugia e A prende 2 monete; in caso contrario, A perde una carta e non ottiene monete, e B deve riportare il proprio Duca sul mazzo e pescare una nuova carta.

Il modo in cui blocchi e sfide funzionano con Assassinate deve essere chiarito. Supponiamo che il Giocatore A dica "Ho un Assassino e Assassino il Giocatore B". Se B non tenta di sfidare o bloccare A, l'assassinio subisce: B perde una carta e A paga 3 monete.

In alternativa, B può sfidare dicendo "Non credo che tu abbia un Assassino". Se questo è vero, allora A scarta una carta e le loro monete vengono restituite, mentre B non viene influenzato e il turno di A termina. Se la convinzione di B è errata e A detiene un Assassino, allora B perde entrambe le carte e fallisce, una per la sfida errata e una per Assassinio.

Invece di sfidare, B potrebbe dire "Ho una contessa e blocco l'assassinio". Se A crede a B, il turno di A termina e le loro monete non vengono restituite. Ma A può sfidare il blocco e dire "Non credo che tu abbia una Contessa." Se B detiene effettivamente una contessa, allora A perde una carta per la sfida errata. Ma se B non lo fa, allora B perde una carta per essere catturato in una bugia e un'altra dall'assassinio.

Una logica simile alla spiegazione precedente si applica all'abilità Rubare del Capitano, in cui l'azione o il blocco possono essere sfidati.

È possibile perdere entrambe le carte ed essere eliminati in un turno, se si sfida un Assassinato senza successo o si viene sorpresi a sostenere che si ha una Contessa per bloccare un Assassinio. Perdi una carta dalla sfida e una carta dall'assassinio.

Sfida

Il tuo compito è quello di scrivere un programma che riprodurrà Coup. Verrà fornito come argomento della riga di comando:

• Il nome di un file contenente l'elenco delle sue azioni e quelle dei suoi avversari finora.
• Un numero intero compreso tra 0 e 12 che indica il conteggio delle monete dell'avversario.
• Un numero intero compreso tra 0 e 12 che indica il conteggio delle monete.
• Una stringa lunga da uno a quattro caratteri che indica le sue carte. Normalmente questa sarà semplicemente una o due carte del tuo programma, ma se il tuo programma è appena riuscito in uno scambio, avrà una lunghezza di n + 2 caratteri, dove n è il tuo numero di carte rimanenti. Il tuo programma deve quindi emettere le n carte che desidera conservare su STDOUT. (I programmi non devono leggere o accedere a STDOUT se non per questo scopo - se si desidera produrre output di debug, scrivere a STDERR.)
• Uno o più argomenti che indicano le mosse legali che può effettuare.

(Esempio di invocazione:, che yourprogram file.txt 1 7 '~!' a c p qsignifica "Il tuo avversario ha 1 moneta. Hai 7 monete, un Ambasciatore e una Contessa. Scrivi su file.txt la tua scelta di a, c, p o q data la storia del gioco e lo stato di gioco attuale. ")

Il programma deve aggiungere uno o (in due situazioni specifiche) due caratteri al file fornito che indica la sua azione. In caso contrario, non deve modificare il contenuto esistente del file. Può creare tutti i nuovi file che desidera, ma solo all'interno della directory in cui viene eseguito. Fornisci tutti i comandi necessari per compilare ed eseguire il tuo programma.

Di seguito ho fornito due esempi di concorrenti, scritti in Go.

Il formato di output è:

• I\n: Reddito. Risposte legali: qualsiasi azione di turno (supponendo che uno abbia le monete per Assassinare / Colpo di stato).
• F: Aiuti esteri. Risposte legali: d(blocca come duca), p(lascialo passare).
• C: Colpo di stato Risposte legali: a seconda di quale di _, ', <, =, 0è nelle tue mani.
• E: Scambio. Risposte legali: q(sfida, non credendo il giocatore ha un ambasciatore), p.
• T: Imposta. Risposte legali: q(sfida, non credendo il giocatore ha un Duke), p.
• A: Assassinare. Risposte giuridiche: s(a blocchi come Contessa), q(sfida), e seconda di quale di _, ', <, =, 0è in mano.
• S: Rubare. Risposte giuridiche: a(a blocchi come un ambasciatore), c(blocco come un capitano), q(sfida, non credendo il giocatore ha un capitano), p.
• d: blocca gli aiuti esteri come duca. Risposte legali: \n(accetta il blocco), q(sfida, non credere che il giocatore abbia un Duca).
• a: blocca un furto come ambasciatore. Risposte legali: \n(accetta il blocco), q(sfida, non credere che il giocatore abbia un Ambasciatore).
• c: blocca un furto come capitano. \n(accetta il blocco), q(sfida, non credere che il giocatore abbia un Capitano).
• s: blocca un Assassinato come Contessa. Risposte legali: \n(accetta il blocco), q(sfida, non credere che il giocatore abbia una contessa).
• p: passa sfidando uno Scambio / Tasse / Ruba quando non è il tuo turno. Non utilizzato con A; rifiutare di sfidare un Assassinio scrivere uno di _'<=0. Risposta legale: \n(termina il tuo turno), e se hai appena avuto successo in uno scambio, scrivi le carte che desideri conservare dal quarto argomento della riga di comando su STDOUT.
• q: sfida l'azione o il blocco più recenti. Risposta legale: se hai la carta per l'azione che è stata contestata, qualunque ~^*!$essa fosse. Se non lo fai, qualunque sia la _'<=0tua mano a cui vuoi rinunciare, seguita da una nuova linea se e solo se è il tuo turno.
• ~, ^, *, !, $: Rivelano che si stava dicendo la verità circa la detenzione, rispettivamente, un ambasciatore, un Assassino, un capitano, un Contessa, e un Duca (utilizzato anche per rappresentare queste carte in argomenti della riga di comando, e STDOUT uscita in scambio ). Risposte legali: a seconda di quale di _, ', <, =, 0che avete in mano.
• _, ', <, =, 0: Rinunciare, come punizione, rispettivamente, un ambasciatore, e assassino, un capitano, un Contessa, e un Duca perché hai perso una sfida o sono stati ASSASSINATO / couped. Risposta giuridica: \n.
• \n: termina il tuo turno, in tal modo diminuendo per sfidare un blocco, se applicabile. Risposte legali: qualsiasi azione in maiuscolo (supponendo che uno abbia le monete per Assassinare / Colpo e l'avversario abbia le monete per Rubare).

Il formato ha le seguenti proprietà utili:

• Le svolte iniziano con una lettera maiuscola.
• Le linee seguono il modello: lettere maiuscole, lettere minuscole, segni di punteggiatura opzionali o 0 per le carte rivelate, riga nuova.
• Un file che termina con una nuova riga o un file vuoto indica che è l'inizio del turno del programma e deve scegliere un'azione in maiuscolo.
• Le azioni legali che è consentito intraprendere su un'invocazione sono generalmente determinate in modo univoco dall'ultimo carattere nel file. L'eccezione è q, a cui sarà associata una logica. Vedi la funzione get_legal_actionsnell'arbitro per capire questo. Oppure puoi semplicemente usare le azioni legali che ti vengono fornite sulla riga di comando.
• Un numero pari di personaggi su una linea indica che il turno è tuo e al tuo programma viene chiesto di scegliere un'azione, sfidare un blocco o terminare il suo turno.
• Un numero dispari di personaggi su una linea indica che il turno non è tuo e al tuo programma viene chiesto di bloccare, sfidare o rivelare / consegnare una carta.

Farò un esempio per ogni azione.

I\nè il più facile da capire. Un programma prende una moneta del reddito, quindi termina il suo turno. Questo è uno dei due casi in cui i programmi devono stampare due personaggi, poiché il reddito è l'unica azione in cui l'avversario non è influenzato e non può bloccare o sfidare.

Fp\nsignifica che un programma ha preso aiuti esteri, quindi il suo avversario ha rifiutato di bloccare ( p). Alla sua successiva invocazione, il primo programma ha notato che dalla lettera minuscola finale pe / o dal numero pari di caratteri su questa linea ha preso questo turno, che non è ancora terminato, quindi sa di terminare il suo turno corrente stampando una nuova riga.

C=\nsignifica che un programma ha lanciato un colpo di stato. Il suo avversario, sapendo che era chiamato a reagire per il numero dispari di lettere sulla linea, rinunciò a una Contessa. Ancora una volta, il primo programma sapeva che questa era la sua svolta incompleta alla sua successiva invocazione dal numero pari di caratteri sulla linea, quindi ha scritto una nuova riga per terminare la sua svolta.

Eq~<\nsignificherebbe che un programma ha tentato uno scambio ( E) e il suo avversario ha sfidato ( q). Il programma di Scambio ha rivelato che aveva davvero un Ambasciatore ( ~) e lo sfidante ha rinunciato a un Capitano come punizione ( <). Dopo che lo sfidante è uscito, il programma di Scambio viene nuovamente invocato con una stringa di quattro caratteri come quarto argomento della riga di comando (o tre caratteri, se avesse solo una carta). Scrive i personaggi che rappresentano le carte che desidera conservare su STDOUT e una nuova riga nel file.

Tq'\nsignifica che un programma ha tentato una tassa non veritiera, è stato sfidato e ha rinunciato a un assassino. Illustra l'altro caso in cui sono scritti due personaggi: se è il tuo turno e sei costretto a rinunciare a una carta - dalla sfida corretta di un avversario (come qui) o dalla sfida errata di un blocco - allora devi scrivere entrambi la carta che abbandoni e una nuova riga per terminare il tuo turno.

Asq!'\nsignificherebbe che il giocatore B ha tentato di assassinare il giocatore A ( A), ma A ha affermato di avere una Contessa per bloccarlo ( s). B non credeva in A e lo sfidava ( q). A ha rivelato che in effetti avevano una Contessa ( !). B rinunciò a un Assassino come punizione, perdendo le monete e finì il loro turno ( '\n), scrivendo due personaggi come in quel caso speciale. (Se A avesse deciso di non bloccare o sfidare, avrebbe potuto scrivere =, e quindi il suo avversario avrebbe visto che il turno era finito e avrebbe scritto una nuova riga. La riga avrebbe quindi letto A=\n, come nell'esempio Coup.)

Sq*0\nsignifica che un programma tenta un furto; l'avversario sfida, non credendo che il ladro abbia un Capitano; e il programma originale rivela un Capitano, quindi la sfida non ha successo e lo sfidante rinuncia a un Duca come punizione. (Un'altra opzione per il suo avversario sarebbe quella di accettare lo Steal scrivendo p. Il suo avversario rileverebbe quindi la fine del suo turno e scriverà \n, risultando in una riga di Sp\n.)

The Arbiter

I programmi saranno richiamati da questo script Python. Conduce dieci round, in cui ogni concorrente affronta tutti gli altri concorrenti, andando sia al primo che al secondo. Tiene traccia delle carte e del conteggio delle monete e determina il perdente dal primo programma per terminare due volte una linea con un segno di punteggiatura. I programmi che escono con uno stato diverso da zero, modificano il file, scrivono una mossa illegale nel file o tentano uno scambio illegale perderanno automaticamente. Se ogni giocatore esegue più di 100 azioni, inclusi blocchi e sfide, senza vincitori, entrambi i programmi perdono. A un vincitore viene assegnato un punto. Vince il giocatore il cui programma segna il maggior numero di punti.

Ti suggerisco di leggere il codice sorgente dell'Arbiter, in particolare la get_legal_actionsfunzione. Può aiutarti a capire le specifiche e scrivere i tuoi programmi.

miscellaneo

Un programma non può avere un codice specifico per un altro programma e i programmi non possono aiutarsi a vicenda. (Potresti avere più programmi, ma non possono interagire tra loro in alcun modo.)

Se il tuo programma perde entrambe le carte nello stesso turno, deve solo scriverne una. L'Arbiter rileverà che è stato eliminato.

È possibile e incoraggiato, ma non necessario, che i programmi esaminino la cronologia del gioco nel file. In questo modo possono determinare quali carte il loro avversario ha affermato di avere e catturarle in una bugia.

Nel vero gioco di Coup, puoi sfidare un'azione e quindi tentare di bloccarla nello stesso turno. Non potrei far funzionare le specifiche se lo consentissi, quindi potresti sfidare o bloccare una determinata azione, ma non entrambe.

Mi scuso con @PeterTaylor, che la volta precedente ho pubblicato questo suggerito di postarlo nella sandbox e rielaborare il protocollo per reindirizzare l'output avanti e indietro in STDOUT / STDIN. Ho provato così, così duramente per farlo funzionare, trascorrendo un'intera giornata (quando avevo già trascorso un'intera giornata a scrivere la sfida originale). Ma gli scambi si sono dimostrati molto complicati da implementare in quel modo, inoltre avrebbe aumentato la complessità degli invii richiedendo loro di tenere traccia del proprio conteggio delle monete. Quindi ho pubblicato la sfida più o meno com'era in origine.

Avvocato

L'avvocato si fa strada cautamente nel mondo, non mentendo mai, bloccando quando possibile, sfidando quando non a suo danno immediato. Non attacca se non quando richiesto dall'accoppiamento, ma prenderà le monete il più spesso possibile per abbattere rapidamente. È abbastanza intelligente da sacrificare le carte che non usa per primo, ma non abbastanza da usarle per sbarazzarsene e ottenerne di nuove.

Probabilmente ci sono bug in questo programma. Quando li trovi, per favore fammi sapere.

Casuale

Casuale non sa cosa fare, quindi seleziona casualmente qualcosa di legale.

package main

import (
    "fmt"
    "math/rand"
    "os"
    "time"
)

func main() {
    rand.Seed(time.Now().UnixNano())
    filename := os.Args[1]
    ourCards := os.Args[4]
    legalActions := os.Args[5:]
    file, _ := os.OpenFile(filename, os.O_WRONLY|os.O_APPEND, 0755)
    defer file.Close()

    file.WriteString(legalActions[rand.Intn(len(legalActions))])
    switch len(ourCards) {
    case 3:
        os.Stdout.Write([]byte{ourCards[rand.Intn(3)]})
    case 4:
        i1 := 0
        i2 := 0
        for ok := true; ok; ok = i1 == i2 {
            i1 = rand.Intn(4)
            i2 = rand.Intn(4)

Challenger non si fida di nessuno in questo gioco dell'inganno. Se fai qualcosa di sfidante, ti sfiderà. Altrimenti prende entrate ogni turno e cerca di farti Coup se ha le monete.

    defer file.Close()

            file.Write([]byte{'C'})
            // We don't, so take income.
        } else {
            file.Write([]byte("I\n"))
        }
    // Opponent did something challengeable. We don't believe them for a second.
    // Challenge it.
    case 'E', 'T', 'A', 'S', 'a', 'c', 'd', 's':
        file.Write([]byte{'q'})
    // Opponent Couped us or our challenge failed. Give up a card.
    case 'C':
        file.Write([]byte{revealToPunishment[ourCards[0]]})
    case '~', '*', '^', '!', '$':
        file.Write([]byte{revealToPunishment[ourCards[0]]})
        lastLine := lines[len(lines)-1]
        switch lastLine[len(lastLine)-3] {
        case 'a', 'c', 'd', 's':
            file.WriteString("\n")
        }
    // Our challenge succeeded or we Couped the opponent! End our turn.
    case '_', '\'', '<', '=', '0':
        file.Write([]byte{'\n'})
    default:

        file.Write([]byte{'p'})
    }
}

Commercialista

Il Taxman è qui per riscuotere le tasse. Usa l'assassino se ne ha uno. Blocca solo se hanno la carta da bloccare. Sfide casuali.

Scritto in c #, ho trascorso troppo tempo a costruire una gerarchia di classi per tutte le diverse azioni che possono essere intraprese.

Modifica: ora con una logica migliorata come non pretendere di avere un duca quando hanno rinunciato a un duca dopo essere stati sfidati. Inoltre, non cerca più di assassinare continuamente se l'avversario blocca con contessa (e non è sfidato).

Maschera

La maschera è un maestro del travestimento. Impedisce agli avversari di tenere traccia delle sue carte Scambiando ogni volta che agisce o blocca. La sua strategia vincente è quella di prendere 3 monete come Duca, quindi Assassinare.
