darse cuenta

Este desafío ha finalizado y no se volverá a juzgar, ¡pero siéntase libre de publicar respuestas y probar su programa contra los demás con el Programa de Control!

El objetivo de este desafío es hacer que una IA gane una pelea contra otra IA dibujando estratégicamente un muro en una cuadrícula de 25x25 para bloquear al oponente.

Entrada

25 líneas separadas por y terminando con ;un argumento de línea de comando. Esto incluirá:

• Espacios vacíos .
• Paredes #
• Jugadores 1y 2(El oponente es siempre 2)

Ejemplo

###############..........;..............#..........;..............#..........;..............#..........;..............#..........;...........1###..........;.........................;.........................;.........................;.........................;.........................;.........................;.........................;.........................;.........................;.........................;.........................;.........................;.........................;...................###...;...................#.##..;2..................#..#..;#..................##.#..;#...................#.###;....................#####;

que representa el siguiente mapa:

Salida

Una cadena escrita en la consola que comienza con el personaje que representa la dirección en la que la IA desea girar. ¡Esto es sensible a mayúsculas y minúsculas!

• norte N
• Este E
• Sur S
• Oeste W
• Renunciar (cualquier otra cosa)

Ejemplo

W

Reglas del juego

• A medida que las IA se mueven, dejarán un rastro sólido de paredes detrás de ellas.
• Los jugadores comienzan en las esquinas superior izquierda e inferior derecha
• El juego dura hasta que cualquier IA golpea una pared o las IA chocan entre sí.
  • Una IA gana si su oponente se estrella primero
  • No hay ganador ni perdedor si las IA pierden al mismo tiempo.
• Si una IA se sale de un borde de la cuadrícula, continúan en la misma dirección desde el otro lado.

Floodbot

Java

Este tipo tiene que ver con la evitación. No le importa tratar de atrapar al oponente, solo quiere vivir. Para hacer eso, inunda cada dirección para ver qué camino conducirá al área abierta más grande.

También cree que el enemigo es impredecible, por lo que trata cada cuadrado que los rodea inmediatamente como si ya fuera un muro. Si eso no conduce a una dirección posible, recurre al mapa "real".

EDITAR 5 : Más consciente del futuro; intenta evitar cerrar áreas (a menos que, por supuesto, el oponente esté en ella).

EDIT 4 : código limpiado.

EDIT 3 : funciona mejor para áreas de juego rectangulares.

EDIT 2 : código más limpio, el algoritmo es más lógico y predice algunos movimientos hacia el futuro

EDITAR : Algoritmo más defensivo, no cuenta al fantasma como espacio vacío.

AusenteBot

escrito en Ruby (1.9)

Bien llamado, AwayBot intenta alejarse de cualquier obstáculo. Busca un cuadrado de 15x15 a su alrededor, pondera las direcciones en consecuencia y elige la dirección con la menor cantidad de obstáculos. (Esto también significa que evita los bordes, lo cual es bueno para que no quede atrapado en ellos).

También considera que las paredes cercanas son más peligrosas. Los muros justo al lado tienen mucho más peso que los muros que están lejos.

Para su entrada de muestra, sale S. Los pesos para cada dirección de la entrada de muestra son [["N", 212], ["E", 140], ["S", 0], ["W", 84]].

Interjección: Acabo de notar que la arena se envuelve. Pues bien, mi técnica para evitar bordes no tiene sentido ahora, pero meh. Tal vez lo arreglemos más tarde.

arena = ARGF.argv[0]

# we're considering the enemy a wall, for simplicity.
# no need to weight him any more than the other walls because he will
# always be surrounded by walls anyway.
arena = arena.sub(?2, ?#).split(?;)

# pad the arena with extra walls (edges of the arena)
searchRadius = 7
arenaSize = arena.first.size

verticalEdgeWalls = [?# * arenaSize] * searchRadius
arena = verticalEdgeWalls + arena + verticalEdgeWalls

horizontalEdgeWalls = ?# * searchRadius
arena.map! {|row| (horizontalEdgeWalls + row + horizontalEdgeWalls).split('') }

# now get the area around the bot
botRow = arena.index{|row| row.index ?1 }
botCol = arena[botRow].index ?1

searchZone = arena.slice(botRow-searchRadius..botRow+searchRadius)
searchZone.map! {|row| row.slice(botCol-searchRadius..botCol+searchRadius) }

# second to last step: assign values to each square depending on how far away they are
# from the player (Manhattan distance)
# this is so that the player avoids running directly into a wall; higher value means closer tile
# 0123210
# 1234321
# 2345432
# 1234321
# 0123210
centerSquare = searchRadius
searchZone = searchZone.each_with_index.map {|row, rowIndex| row.each_with_index.map{|tile, tileIndex|
    [tile, searchRadius*2 - ((rowIndex - centerSquare).abs + (tileIndex - centerSquare).abs)]
} }
puts searchZone.map{|x|x.map{|y|y[1].to_s.rjust(2, ?0)}.join ' '} * "\n"

# finally, assign weights to each direction
# first, create a map of directions. each direction has an array, the first element being
# what rows to slice and the second being what column.
sBeg = 0
sMdl = searchRadius
sEnd = searchRadius*2
directions = {
    ?N => [sBeg..sMdl-1, sBeg..sEnd],
    ?E => [sBeg..sEnd, sMdl+1..sEnd],
    ?S => [sMdl+1..sEnd, sBeg..sEnd],
    ?W => [sBeg..sEnd, sBeg..sMdl-1]
}
# then, create another hash of weights
weights = directions.map{|dir, arr|
    section = searchZone.slice(arr[0]).map{|x| x.slice(arr[1]) }.flatten(1)
    [dir, (section.select{|tile| tile[0] == ?# }.map{|tile| tile[1] }.reduce(:+) || 0)] # return the sum of the values of the walls in the area
}
# yay! we have our weights! now just find the smallest one...
dirToGo = weights.min_by{|_, walls| walls }
# and output!
print dirToGo[0]

Arcbot

Python 3

Juega con un algoritmo basado en la agresión mientras el enemigo y las fuerzas brutas responden con influencia

Supongo que este algoritmo está 'basado en la emoción'. Al desarrollar esto, me di cuenta de que FluidBot lo venció casi siempre. Arcbot no es el algoritmo más rápido ni el mejor, pero tiene sus puntos fuertes.

Se hace chocar contra las paredes. No tengo idea de por qué.

FLUIDBOT ES MEJOR

#   Arcbot
#   
#   This is a more dynamic bot than the earlier Fluidbot.
#   I'm also commenting on the code to make my algorithm
#   more clear.
