GAMUT

• A software for generating games

▫ Can generate both normal (strategic) form and extensive (tree) form gamesextensive (tree) form games

• Available as a jar file

• Basic command (from command line):java –jar gamut.jar –g <Name of Game Class>

• Example (Battle of Sexes)java –jar gamut.jar –g BattleOfTheSexes

Command Line Options in GAMUT

• -g: which game class or classes to use• -random_seed: uses system time by default; user

supplied seed can be used to regenerate same instance of gameinstance of game

• -f: output file name• -output: format of output file (default to

SystemOutput; GambitOutput can also be used)• -normalize: normalize the output within range -min_payoff and -max_payoff

• -int_payoffs: generates payoffs as integers• -int_mult: multiplier to use to generate integers

from real values while using -int_payoffs
