gambit-ipa: Compute Nash equilibria in a strategic game using iterated polymatrix approximation

gambit-ipa reads a game on standard input and computes Nash equilibria using an iterated polymatrix approximation approach developed by Govindan and Wilson [GovWil04]. This program is a wrapper around the Gametracer 0.2 implementation by Ben Blum and Christian Shelton.

-d

Express all output using decimal representations with the specified number of digits.

-h

Prints a help message listing the available options.

-q

Suppresses printing of the banner at program launch.
