Sei un commerciante straniero, sperando di realizzare un profitto. Ci sono 5 beni che le persone desiderano scambiare: Aprezzi, Bremi,C anaries, Daffodils e Earwigs. A partire dall'inverno, devi decidere cosa produrre. Quindi, in autunno, viaggi e trascorri le tue giornate facendo trading per ottenere un profitto.

gameplay

Inizi il gioco con 10 di ogni prodotto in deposito. Ogni anno, consumerai 2 di ogni prodotto.

All'inizio del gioco, ricevi un elenco di 5 prodotti, insieme all'importo che potrai produrre ogni anno (es:5-A,6-B,3-C,12-D,4-E . Restituirai quindi una lettera da A a E che decide cosa produrre.

Quindi, in autunno, commercializzerai i tuoi prodotti (compresi quelli in deposito). Hai 50 turni da scambiare.

È necessario decidere se si vuole Purchase, Sell o Lgronda il mercato. Gli acquirenti verranno quindi accoppiati in modo casuale con i venditori. Se un gruppo ha un extra, gli extra casuali perderanno questo turno. Se un commerciante viene saltato, riceveranno S, in caso contrario, T. Il venditore deve decidere ciò che vuole vendere, l'importo (es:) 3-A, e poi cosa accetterebbe (es:) 5-B,2-D,1-E(i valori sono tutti non tutti ). All'acquirente verrà quindi comunicato quale prodotto sta vendendo il venditore, quindi i prodotti che il venditore prenderà per esso e potrà scegliere un prodotto da scambiare per esso (es: Do Xper niente).

Al termine di tutte le negoziazioni o dopo aver lasciato il mercato, consumerai 2 di ciascun prodotto e l'anno ricomincerà. Se hai meno di 2 prodotti su 1, morirai (e passerai Q).

Il tuo punteggio sarà il numero di anni che hai trascorso e dopo 50 partite, i tuoi punteggi saranno mediati per il tuo punteggio totale.

Mosse opzionali

In qualsiasi momento è possibile restituire Gper richiedere la merce

In qualsiasi momento puoi tornare Na richiedere il numero di nuovi prodotti nel tuo inventario (prodotto da qualsiasi giocatore nell'ultimo anno e i nuovi prodotti verranno scambiati prima dei vecchi prodotti)

In qualsiasi momento puoi tornare Talla frase Turn corrente: Produce, arket Mo Trading

Durante uno scambio, puoi fare una query I richiedere un identificatore univoco per il giocatore con cui stai commerciando.

Durante uno scambio, puoi tornare Ma interrogare il numero di persone che fanno trading

Come codificarlo:

È possibile utilizzare qualsiasi linguaggio standard e deve includere un command.txtquale è il comando per eseguire il programma.

Il flusso generale del tuo programma dovrebbe essere:

Get productivity
While alive:
    Output product you want to produce
    While in trading:
        Output whether you want to purchase or sell
        Get whether or not you were skipped.  If not skipped:
            If purchasing:
                print product you offer, and products you will accept
            Else:
                Get product offered, products being accepted, and choose the product you will give

Ho un programma di tester qui . Per usarlo, crea una cartella nella cartella bot con il nome del tuo bot. Aggiungi a command.txt, il tuo programma e qualsiasi altra cosa di cui il tuo programma abbia bisogno. Aggiungerò i contributi non appena arrivano. Se non si desidera installare le lingue necessarie per eseguirne alcune o tutte, è sufficiente eliminare command.txt nella cartella del bot.

Funzionamento interno

Ci saranno 5 robot per ciascun programma inviato. L'ID sarà diverso per i robot dello stesso tipo.

Chiamerò la quantità che una persona può produrre un determinato prodotto, la produttività. Ad ogni prodotto verrà assegnata una produttività di base, in cui tutta la produttività di base sarà pari a 30. Uno dei punteggi sarà garantito per un massimo di 3 e tutti saranno almeno 2.

Quindi, la produttività di ciascun giocatore varierà dalla produttività di base (un valore varierà di +2, un altro +1, quindi +0, -1 e il valore rimanente varierà di -2).

La produttività di base cambierà da gioco a gioco.

I punteggi:

seer:                10.128 years
level_headed_trader: 8.196 years
introvert:           6.856 years

Questo programma predice il futuro e sceglie le operazioni che aumenteranno la sua durata prevista.

Questo non è completamente finito, perché sa solo comprare cose ma non vendere cose, quindi aspettati un aggiornamento in futuro. Indipendentemente da ciò, credo che sarà competitivo così com'è.

Gli agricoltori della famiglia - Java

Tuttavia, dopo gli incarichi iniziali, tutti i membri della famiglia escono da soli; non colludono dopo gli incarichi iniziali. Potrei cercare di aiutarli a vicenda mentre fanno trading.

Ando casuale

Ogni KOTH dovrebbe avere un bot casuale. Speriamo che sia codificato, in modo da non fare affari non validi (come cercare di vendere più di quello che ha in magazzino).
