ESS {EvolutionaryGames}

ESS for two-player games with a maximum of three strategies

Description

Computes Evolutionary Stable Strategies of a game with two players and a maximum of three strategies.

Usage

ESS(A, strategies = c(), floats = TRUE)

Arguments

A

Numeric matrix of size 2x2 or 3x3 representing the number of strategies of a symmetric matrix game.

strategies

String vector of length n that names all strategies whereas n represents the number of strategies.

floats

Logical value that handles number representation. If set to TRUE, floating-point arithmetic will be used, otherwise fractions. Default is TRUE.

Value

Numeric matrix. Each row represents an ESS.
