 In the game theory, we deal with problems like finding equilibrium, evolutionarily stable strategies, stable matching, fair division, bankruptcy, voting, etc. In this package, we are implementing the algorithms proposed for these problems. For example, a function that finds the stable matching for marriage problem with the Gale-Shapley algorithm.
