2. GAMUT
•
A software for generating games ▫ Can generate both normal (strategic) form and
extensive (tree) form games extensive (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

3. 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 game instance of game
•
-f: output file name
•
-output: format of output file (default to
SystemOutput; GambitOutputcan also be used) •
-normalize: normalize the output within range -
min_payoffand-max_payoff •
-int_payoffs: generates payoffs as integers
•
-int_mult: multiplier to use to generate integers
from real values while using 3 int_payoffs
