Game Theory: GameTracer
Ben Blum,
Daphne Koller,
Christian Shelton
GameTracer is an application for calculating Nash equilibria in
normal-form games. It implements the global Newton method of Govindan
and Wilson (2001), as well as their iterative polymatrix approximation
algorithm, a faster method without any theoretical guarantee
of convergence. GameTracer is released under the GNU license, and can
be compiled under Linux or Solaris. Unpack the archive into a
directory and read the README for installation instructions.

NOTE: GameTracer has been updated to compile with GCC version 3.2.2 in Linux and will no longer be tested under Solaris.

The GNM algorithm is outlined in a paper by Srihari Govindan and
Robert Wilson titled A global Newton method to compute Nash equilibria. It will appear in the Journal of Economic Theory in
2003.
The IPA algorithm is outlined in a companion to the above paper, also by Govindan and Wilson, titled Computing Nash Equilibria by Iterated
Polymatrix Approximation. It will appear in the Journal of Economic
Dynamics and Control in 2003.
