game_resolver

This library is internal library for nishino-lab(The University of Tokyo)

Run Sample Game

This library has three type sample games(prisoner, battle of sex, cournot).

from game_resolver.games.custom_game import Prisoner
from game_resolver.nash_equilibrium import NashEquilibrium

prisoner = Prisoner()
ne = NashEquilibrium()
eq = e.get_equilibrium(g)
for i in eq:
    print(i)

Run your own game

A Nash equilibrium can be solved by representing the problem to be solved in the Game class.
