Você é um comerciante estrangeiro, na esperança de obter lucro. Existem cinco produtos que as pessoas desejam comercializar: Apricots, Bremos, Canários, Dafodils e Earwigs. A partir do inverno, você precisa decidir o que produzir. Então, no outono, você viaja e passa seus dias negociando com lucro.

Jogabilidade

Você inicia o jogo com 10 de cada produto em armazenamento. A cada ano, você consumirá 2 de cada produto.

No início do jogo, você recebe uma lista de 5 produtos, juntamente com a quantidade que poderá produzir a cada ano (ex:) 5-A,6-B,3-C,12-D,4-E. Você retornará uma letra A a E decidindo o que produzir.

Então, no outono, você levará seus produtos (incluindo aqueles armazenados) ao mercado. Você tem 50 turnos para negociar.

Você deve decidir se deseja Pcomprar, vender Sou Lvender o mercado. Os compradores serão emparelhados aleatoriamente com os vendedores. Se um grupo tiver extra, os extras aleatórios perderão este turno. Se um comerciante for ignorado, ele receberá S, caso contrário T,. O vendedor deve decidir o que ele quer vender e o valor (ex .:) 3-Ae, em seguida, o que ele aceitaria (ex:) 5-B,2-D,1-E(os valores são alguns de não todos ). O comprador será informado sobre o produto que o vendedor está vendendo, os produtos que o vendedor levará para ele e ele poderá escolher um produto para negociá-lo (ex: Dou Xpor nada).

Depois que todas as negociações terminarem, ou depois de sair do mercado, você consumirá 2 de cada produto e o ano começará novamente. Se você tiver menos de 2 de qualquer 1 produto, morrerá (e será aprovado Q).

Sua pontuação será o número de anos que você durou e, após 50 jogos, sua pontuação será calculada para sua pontuação total.

Movimentos opcionais

A qualquer momento, você pode retornar Gpara consultar suas mercadorias

A qualquer momento, você pode retornar Npara consultar o número de novos produtos em seu inventário (produzido por qualquer jogador no ano passado e novos produtos serão negociados antes dos produtos antigos)

A qualquer momento, você pode retornar Tpara a frase de curva atual: Produce, Market ou Trading

Durante uma negociação, você pode consultar Ium identificador exclusivo para o jogador com quem está negociando.

Durante uma negociação, você pode retornar Mpara consultar o número de pessoas que negociam

Como codificá-lo:

Você pode usar qualquer idioma padrão e deve incluir um command.txtcomando para executar seu programa.

O fluxo geral do seu programa deve ser:

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

Eu tenho um programa de teste aqui . Para usá-lo, crie uma pasta na pasta bots com o nome do seu bot. Adicione a command.txt, seu programa e qualquer outra coisa que seu programa precise. Estarei adicionando envios à medida que eles chegarem. Se você não deseja instalar os idiomas necessários para executar alguns ou todos eles, basta excluir o command.txt na pasta do bot.

Trabalhos internos

Haverá 5 bots para cada programa enviado. O ID será diferente para bots do mesmo tipo.

Vou chamar a quantidade que uma pessoa pode produzir de um determinado produto de produtividade. Cada produto terá uma produtividade básica, onde toda a produtividade básica será de até 30. Uma das pontuações será garantida em no máximo 3 e todas serão no mínimo 2.

Então, a produtividade de cada jogador varia em relação à produtividade base (um valor varia em +2, outro +1, depois em +0, -1 e o valor restante varia em -2).

A produtividade básica mudará de jogo para jogo.

Vidente

Este programa prevê o futuro e ele escolhe os negócios que aumentarão sua expectativa de vida.

Isso não está completamente concluído, porque ele sabe apenas comprar, mas não vender, portanto, espere uma atualização no futuro. Independentemente disso, acredito que ele será competitivo como está.
