Reglas de juego

Coup es un juego de cartas diseñado para 2-6 jugadores, que jugaremos con dos. Consiste en un tesoro de monedas (infinito para nuestros propósitos) y un mazo de 15 cartas, que contiene 3 de cada uno de los siguientes tipos: Embajador, Asesino, Capitán, Contessa, Duque. Al comienzo del juego, cada jugador recibe una moneda y reparte dos cartas al azar, que mantienen en secreto hasta que sea necesario. El objetivo es ser el último jugador con cartas en tu mano.

En su turno, un jugador puede realizar una de las siguientes acciones independientemente de sus cartas:

• Ingresos: toma 1 moneda del tesoro. Desbloqueable e indiscutible.
• Ayuda extranjera: toma 2 monedas del tesoro. Puede ser bloqueado por un jugador con un duque. Inquebrantable
• Golpe: Retira del juego una carta de un oponente de tu elección. Cuesta 7 monedas. La víctima puede elegir qué carta descartar. Si un jugador tiene 10 o más monedas al comienzo de su turno, debe Golpear. Desbloqueable e indiscutible.

Dependiendo de sus cartas, los jugadores también pueden tomar una de las siguientes acciones como su turno:

• Intercambio: un jugador con un Embajador puede tomar dos cartas del mazo. Luego pueden elegir de su mano y de las cartas extraídas tantas cartas como tenían originalmente. (Es decir, si solo tenían una carta, pueden cambiarla por una de las cartas robadas o conservarla, y si tuvieran dos cartas, pueden elegir cualquiera de las cuatro cartas). Las dos cartas no deseadas se devuelven al mazo. . Desbloqueable, pero desafiante.
• Asesinar: un jugador con un Asesino puede gastar 3 monedas para eliminar una carta del oponente del juego. La víctima puede elegir qué carta descartar. Puede ser bloqueado por un jugador con una Contessa, en cuyo caso las monedas no se devuelven. Desafiable, en cuyo caso se devuelven las monedas .
• Robar: Un jugador con un Capitán puede tomar dos monedas de su oponente. Si el oponente tiene una moneda, tomará esa moneda. Si el oponente tiene cero monedas, no puede robar. Puede ser bloqueado por un jugador con un embajador o un capitán. Desafiable
• Impuesto: un jugador con un duque puede tomar 3 monedas del tesoro. Desbloqueable, pero desafiante.

¡La parte difícil de Coup es que los jugadores pueden mentir sobre las cartas que tienen! No es necesario tener una tarjeta para intentar realizar la acción o el bloqueo asociado a ella.

Cuando un jugador realiza la acción de una carta, cualquier oponente (incluso uno que no sea dañado por esa acción) puede desafiar al actor y decir que no cree que tenga la carta para esa acción. Si el retador es correcto, la acción se cancela y el actor debe descartar una carta de su elección (recuperando las monedas que gastaron si corresponde). Si no es así, se toma la acción, el actor devuelve la carta sobre la que fueron desafiados a la baraja y roba una nueva, y el retador debe descartar una de sus cartas. Los jugadores deben ser sinceros acerca de qué cartas tienen cuando son desafiados.

Las cartas eliminadas del juego con Assassinate, Golpe y desafíos perdidos no se devuelven al mazo, pero las cartas reveladas como parte de un desafío ganado se devuelven al mazo.

Los bloques pueden ser desafiados al igual que las acciones. Por ejemplo, si el jugador A reclama Ayuda Extranjera y el jugador B dice "Tengo un Duque y bloqueo tu Ayuda Extranjera", A puede decir "No creo que tengas un Duque". Si esa afirmación es correcta, B pierde una carta por ser atrapado en una mentira y A toma 2 monedas; si no es así, A pierde una carta y no recibe monedas, y B debe devolver a su Duque al mazo y robar una nueva carta.

La forma en que funcionan los bloques y los desafíos con Assassinate debe desarrollarse. Supongamos que el Jugador A dice "Tengo un Asesino y Asesino al Jugador B". Si B no intenta desafiar o bloquear a A, entonces el asesinato pasa: B pierde una carta y A paga 3 monedas.

Alternativamente, B puede desafiar diciendo "No creo que tengas un Asesino". Si eso es cierto, entonces A descarta una carta y sus monedas son devueltas, mientras que B no se ve afectado y el turno de A termina. Si la creencia de B es incorrecta y A tiene un Asesino, entonces B pierde ambas cartas y falla, una por el desafío incorrecto y otra por el Asesinato.

En lugar de desafiar, B podría decir "Tengo una Contessa y bloqueo el Asesinato". Si A cree en B, entonces el turno de A termina y no se devuelven sus monedas. Pero A puede desafiar el bloqueo y decir "No creo que tengas una Contessa". Si B tiene una Contessa, entonces A pierde una carta por el desafío incorrecto. Pero si B no lo hace, entonces B pierde una carta por ser atrapado en una mentira y otra por el Asesinato.

Una lógica similar a la explicación anterior se aplica a la habilidad Robar del Capitán, donde la acción o el bloqueo pueden ser desafiados.

Es posible perder ambas cartas y ser eliminado en un turno, si desafías sin éxito a un Asesino o si te atrapan diciendo falsamente que tienes una Contessa para bloquear un Asesinato. Pierdes una carta del desafío y una carta del Asesinato.

Desafío

Su tarea es escribir un programa que juegue Coup. Se dará como argumentos de línea de comando:

• El nombre de un archivo que contiene la lista de sus acciones y las de sus oponentes hasta el momento.
• Un número entero de 0 a 12 que indica el recuento de monedas del oponente.
• Un entero de 0 a 12 que indica su recuento de monedas.
• Una cadena de uno a cuatro caracteres que indica sus cartas. Normalmente, esta será simplemente una o dos tarjetas que tiene su programa, pero si su programa acaba de tener éxito en un intercambio, tendrá una longitud de n + 2 caracteres, donde n es el número de tarjetas que le quedan. Su programa debe generar las n tarjetas que desea mantener en STDOUT. (Los programas no deben leer ni acceder a STDOUT de otra manera que no sea para este propósito; si desea generar resultados de depuración, escriba a STDERR).
• Uno o más argumentos que indican los movimientos legales que puede hacer.

(Ejemplo de invocación: yourprogram file.txt 1 7 '~!' a c p qsignifica "Tu oponente tiene 1 moneda. Tienes 7 monedas, un Embajador y una Contessa. Escribe en archivo.txt tu elección de a, c, p o q dado el historial de juego y el estado actual del juego. ")

Su programa debe agregar uno o (en dos situaciones específicas) dos caracteres al archivo proporcionado que indica su acción. De lo contrario, no debe alterar el contenido existente del archivo. Puede crear cualquier archivo nuevo que desee, pero solo dentro del directorio en el que se ejecuta. Proporcione todos los comandos necesarios para compilar y ejecutar su programa.

He proporcionado dos ejemplos de competidores a continuación, escritos en Go.

El formato de salida es:

• I\n: Ingresos. Respuestas legales: cualquier acción de turno (suponiendo que uno tenga las monedas para Assassinate / Coup).
• F: Ayuda externa. Respuestas legales: d(bloquear como duque), p(dejarlo pasar).
• C: Golpe de Estado. Respuestas legales: aquel de _, ', <, =, 0está en tu mano.
• E: Intercambio. Respuestas legales: q(desafío, no creer que el jugador tiene un embajador), p.
• T: Impuestos. Respuestas legales: q(desafío, no creer que el jugador tiene un Duke), p.
• A: Asesinar. Respuestas legales: s(bloque como Contessa), q(desafío), y cualquiera de _, ', <, =, 0que está en su mano.
• S: Robar. Respuestas legales: a(bloque como Embajador), c(bloque como capitán), q(desafío, no creer que el jugador tiene un capitán), p.
• d: bloquear la ayuda extranjera como duque. Respuestas legales: \n(acepta el bloqueo), q(desafía, sin creer que el jugador tiene un duque).
• a: bloquear un robo como embajador. Respuestas legales: \n(acepta el bloqueo), q(desafía, sin creer que el jugador tiene un Embajador).
• c: bloquear un robo como capitán. \n(acepta el bloqueo), q(desafía, sin creer que el jugador tiene un Capitán).
• s: bloquea a un Asesino como Contessa. Respuestas legales: \n(acepta el bloqueo), q(desafía, sin creer que el jugador tiene una Contessa).
• p: pase desafiando un Intercambio / Impuesto / Robo cuando no es su turno. No se usa con A; negarse a desafiar un asesinato escriba uno de _'<=0. Respuesta legal: \n(finaliza tu turno), y si acabas de tener éxito en un intercambio, escribe las cartas que deseas conservar desde el cuarto argumento de la línea de comando hasta STDOUT.
• q: desafía la acción o bloque más reciente. Respuesta legal: si tiene la tarjeta para la acción que fue impugnada, la que ~^*!$sea. Si no lo hace, entonces cualquiera de _'<=0su mano a la que desee renunciar, seguido de una nueva línea si es su turno.
• ~, ^, *, !, $: Revelar que ha dicho la verdad sobre la celebración, respectivamente, un embajador, un asesino, un capitán, una condesa, y una de Duke (también se utiliza para representar estas tarjetas en los argumentos de línea de comandos, y la salida estándar de salida en un Intercambio ) Respuestas legales: aquel de _, ', <, =, 0que tiene en su mano.
• _, ', <, =, 0: Renunciar como castigo, respectivamente, un embajador, y el asesino, un capitán, una condesa, y una de Duke porque perdió un reto o fueron asesinados / couped. Respuesta legal: \n.
• \n: finaliza tu turno, al hacerlo, rechazas desafiar un bloque si corresponde. Respuestas legales: cualquier acción de mayúscula (suponiendo que uno tenga las monedas para Assassinate / Coup y el oponente tenga las monedas para Steal).

El formato tiene las siguientes propiedades útiles:

• Los turnos comienzan con una letra mayúscula.
• Las líneas siguen el patrón: letras mayúsculas, letras minúsculas, opcionalmente signos de puntuación o 0 para tarjetas reveladas, nueva línea.
• Un archivo que termina con una nueva línea, o un archivo vacío, indica que es el comienzo del turno de su programa y debe elegir una acción de mayúscula.
• Las acciones legales que puede realizar en una invocación generalmente están determinadas de forma única por el último carácter del archivo. La excepción es q, que tendrá algo de lógica asociada. Vea la función get_legal_actionsen el árbitro para ayudar a entender esto. O simplemente puede usar las acciones legales que se le dan en la línea de comando.
• Un número par de caracteres en una línea indica que el turno es suyo y se le pide a su programa que elija una acción, desafíe un bloqueo o finalice su turno.
• Un número impar de caracteres en una línea indica que el turno no es tuyo y se le pide a tu programa que bloquee, desafíe o revele / entregue una carta.

Daré un ejemplo para cada acción.

I\nEs el más fácil de entender. Un programa toma una moneda de Ingresos, luego termina su turno. Este es uno de los dos casos en que los programas deben imprimir dos caracteres, ya que Ingresos es la única acción en la que el oponente no se ve afectado y no puede bloquear ni desafiar.

Fp\nsignifica que un programa recibió ayuda extranjera, luego su oponente se negó a bloquear ( p). En su próxima invocación, el primer programa señaló que por la letra minúscula final py / o el número par de caracteres en esta línea tomó este turno, que aún no ha finalizado, por lo que sabe finalizar su turno actual imprimiendo una nueva línea.

C=\nsignifica que un programa lanzó un golpe. Su oponente, sabiendo que fue llamado a reaccionar por el número impar de letras en la línea, renunció a una Contessa. Nuevamente, el primer programa sabía que este era su turno incompleto en su próxima invocación por el número par de caracteres en la línea, por lo que escribió una nueva línea para finalizar su turno.

Eq~<\nsignificaría que un programa intentó un intercambio ( E) y su oponente desafió ( q). El programa de Intercambio reveló que sinceramente tenía un Embajador ( ~) y el retador entregó un Capitán como castigo ( <). Después de que el retador sale, el programa de Intercambio se invoca nuevamente con una cadena de cuatro caracteres como su cuarto argumento de línea de comando (o tres caracteres, si solo tuviera una carta). Escribe los caracteres que representan las tarjetas que desea conservar en STDOUT y una nueva línea en el archivo.

Tq'\nsignifica que un programa intentó un impuesto falso, fue desafiado y renunció a un Asesino. Ilustra el otro caso en el que se escriben dos personajes: si es tu turno y estás obligado a renunciar a una carta, ya sea del desafío correcto de un oponente (como aquí) o de tu desafío incorrecto de un bloque, entonces debes escribir ambos la carta que abandonas y una nueva línea para finalizar tu turno.

Asq!'\nsignificaría que el jugador B intentó asesinar al jugador A ( A), pero A afirmó tener una Contessa para bloquearlo ( s). B no le creyó a A y desafió ( q). A reveló que, de hecho, tenían una Contessa ( !). B entregó un Asesino como castigo, perdiendo sus monedas, y terminó su turno ( '\n), escribiendo dos personajes como en ese caso especial. (Si A hubiera decidido no bloquear o desafiar, podría haber escrito =, y luego su oponente habría visto que el turno había terminado y escrito una nueva línea. La línea habría leído A=\n, como el ejemplo del Golpe de Estado).

Sq*0\nsignifica que un programa intenta un robo; el oponente desafía, sin creer que el ladrón tiene un Capitán; y el programa original revela un Capitán, por lo que el desafío no tiene éxito y el retador renuncia a un Duque como castigo. (Otra opción para su oponente sería aceptar el Steal por escrito p. Su oponente detectaría el final de su turno y escribiría \n, lo que daría como resultado una línea de Sp\n).

El árbitro

Los programas serán invocados por este script de Python. Lleva a cabo diez rondas, en las que cada competidor se enfrenta a todos los demás competidores, yendo primero y segundo. Realiza un seguimiento de los recuentos de cartas y monedas y determina el perdedor por el primer programa para finalizar una línea con un signo de puntuación dos veces. Los programas que salen con un estado distinto de cero, modifican el archivo, escriben un movimiento ilegal en el archivo o intentan un intercambio ilegal se perderán automáticamente. Si cada jugador realiza más de 100 acciones, incluidos bloqueos y desafíos, sin ganador, ambos programas pierden. Un ganador recibe un punto. El jugador cuyo programa obtenga la mayor cantidad de puntos gana.

Le sugiero que lea el código fuente del árbitro, especialmente la get_legal_actionsfunción. Puede ayudarlo a comprender la especificación y escribir sus propios programas.

Diverso

Un programa no puede tener código específico para otro programa, y ​​los programas no pueden ayudarse entre sí. (Es posible que tenga varios programas, pero no pueden interactuar entre sí de ninguna manera).

Si su programa pierde ambas cartas en el mismo turno, solo necesita escribir una. El árbitro detectará que ha sido eliminado.

Es posible y alentado, pero no es obligatorio, que los programas examinen el historial del juego en el archivo. Al hacerlo, pueden determinar qué cartas ha afirmado tener su oponente y atraparlas en una mentira.

En el juego real de Coup, puedes desafiar una acción y luego intentar bloquearla en el mismo turno. No podría hacer que la especificación funcione si lo permitiera, por lo que puede desafiar o bloquear una acción determinada, pero no ambas.

Mis disculpas a @PeterTaylor, quien en la última vez que publiqué esto sugirió que lo publique en la caja de arena y vuelva a trabajar el protocolo para canalizar la salida de un lado a otro en STDOUT / STDIN. Lo intenté, muy duro, para hacer que eso funcionara, pasando un día completo (cuando ya había pasado un día completo escribiendo el desafío original). Pero los intercambios resultaron muy complicados de implementar de esa manera, además habría aumentado la complejidad de las presentaciones al exigirles que realicen un seguimiento de su propio recuento de monedas. Así que publiqué el desafío más o menos como era originalmente.

Abogado

El Abogado se abre paso con cautela por el mundo, nunca miente, bloquea cuando es posible, desafía cuando no es en detrimento inmediato. No ataca, excepto cuando es requerido por el golpe, pero tomará monedas con la mayor frecuencia posible para golpear rápidamente. Es lo suficientemente inteligente como para sacrificar cartas que no usa primero, pero no lo suficientemente inteligente como para usarlas para deshacerse de ellas y obtener otras nuevas.

Aleatorio

Random no sabe qué hacer, por lo que selecciona aleatoriamente algo legal.

package main

    "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) {

Recaudador de impuestos

El recaudador de impuestos está aquí para recaudar impuestos. Utiliza asesino si tienen uno. Solo bloquea si tienen la tarjeta para bloquear. Desafíos al azar.

Escrito en C #, pasé demasiado tiempo creando una jerarquía de clases para todas las diferentes acciones que se pueden tomar.

Editar: ahora con una lógica mejorada, como no pretender tener un duque cuando han renunciado a un duque después de ser desafiados. Además, ya no intenta asesinar continuamente si el oponente bloquea con contessa (y no es desafiado).

Máscara

La máscara es un maestro del disfraz. Evita que los oponentes sigan sus cartas intercambiando cada vez que actúa o bloquea. Su estrategia ganadora es tomar 3 monedas como el duque, luego asesinar.
