All releases of Gambit
Release Notes: This release fixes some minor bugs and adds a few minor graphical interface enhancements as part of refactoring the internals to make building a publicly-documented library for the next release cycle. (The library is built, but not documented now; see the libgambit directory in the source distribution.) New implementations of four algorithms have been added, quantal response tracing, a heuristic support-search method, and the global Newton and iterated polymatrix methods of Govindan and Wilson.
Release Notes: This release fixes some outstanding minor bugs and continues the polishing of the graphical interface, with special focus on ease of use for the beginning student of game theory. Strategic games are now presented in a flexible contingency table format, so that the entire game table is presented on the screen at the same time, even for N-player games. Payoffs in extensive games are now edited directly on the display of the game tree, instead of in a separate dialog. Finally, this version introduces a new extended file format.
Release Notes: This release presents several significant enhancements for computing Nash equilibria. New implementations of Govindan and Wilson's Global Newton and Iterated Polymatrix algorithms are provided, based on gametracer. EnumMixed has been extended to compute the structure of components of Nash equilibria in degenerate games, and Simpdiv has been augmented to allow any strategy profile as a starting point.
Release Notes: This release reorients the codebase for greater flexibility. It now builds a library of code suitable for linking in other programs, as well as a complete Python interface to the API. Documentation of the API is now also available.
Release Notes: Minor bugfixes and feature enhancements were made, including support for exporting normal form games to HTML and to Martin Osborne's LaTeX style. An unhandled exception that occurred when viewing a report on a profile whose test for trembling-hand perfection had not been done was fixed. The graphical interface now loads and displays large game trees faster. Changes were made for compatibility with GCC 3.3.
Release Notes: Notable in this version is some further enhancement in customizing plots of logit equilibrium correspondences, in particular the ability to export these to image files or PostScript. Internally, class names have been (almost universally) standardized to what will be more or less their final values. This version builds with wxWindows libraries compiled with Unicode support,. This version also incorporates bugfixes and enhancements from stable versions 0.97.0.4 and 0.97.0.5.
Release Notes: This release fixes a few graphical interface bugs and misfeatures. A crash caused when editing profile probabilities has been eliminated. Most algorithms now return any equilibria computed so far when Cancel is pressed. Tests for trembling-hand perfection are suppressed in many cases (especially on large games, where these tests are expensive). You'll want to upgrade if you use Gambit on large games, or if you do any custom editing of strategy profiles.
Release Notes: This is a minor bugfix and major portability fix release. It includes support for compilation under FreeBSD and MacOS X. The code to export pictures of extensive form games to graphics files has been backported from the development versions. This release also implements a few tweaks to resolve items listed in the bug tracker. All of these items were primarily cosmetic in nature, and do not affect the correct operation of the programs.
Release Notes: 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).
Release Notes: A few minor bugs that could cause the GUI to crash were fixed.
