Gambit is a set of tools for doing game theory on
finite games. It features a graphical interface as
well as a (currently experimental) Python API for
doing repetitive or econometric tasks on games.
Information regarding Project Releases and Project Resources. Note that the information here is a quote from Freecode.com page, and the downloads themselves may not be hosted on OSDN.
There is a new experimental Python API, plus rationalization of the C++ API. There are more flexible GUI internals for future expansion. Yamamoto's algorithm for computing a proper equilibrium can be used (alpha status currently).
