1. Trade Network Game (TNG) and SimBioSys

The Trade Network Game (TNG) is a framework for studying the formation and evolution of trade networks among strategically interacting traders (buyers, sellers, and dealers) operating under variously specified market protocols. Successive generations of resource-constrained traders choose and refuse trade partners on the basis of continually updated expected utility, engage in trade interactions modelled as 2-person games, and evolve their trade strategies over time. The TNG framework permits evolutionary outcomes to be studied at four different levels: trader attributes (endogenous evolution of personality types); trade network formation (who is trading with whom, and with what regularity); expressed trade behavior (cooperative, predacious,...); and individual and social welfare measures (market efficiency, market power, individual utility levels,...).

2. Extensive Form Game Applet

This applet allows you to create extensive-form (sequential) games, and have them automatically solved for you. The applet allows up to four players, and up to 14 periods. To use the applet, follow the four steps along the right side of the screen: Pick a prototype game tree. Customize the tree to look like your game Add payoffs Solve To customize the game tree (step two), select a node and drag it, or select "add child" to add a sub-node, or "remove node" to delete it.

3. Gambit: Solvers and Analysers

Gambit is a library of game theory software and tools for the construction and analysis of finite extensive and normal form games. Gambit is designed to be portable across platforms: it currently is known to run on Linux, FreeBSD, MacOS X, and Windows 98 and later. Gambit provides: 1. A graphical user interface, based upon the wxWidgets (nee wxWindows) library, providing a common look-and-feel across platforms; 2. A Python API for scripting applications (under development); 3. A library of C++ source code for representing games, suitable for use in other applications. [Details...]

4. Game Theory Simulation Software

There are correspondingly two types of software available from this page: the Spatial Games software, as the name indicates, simulates a game with strong spatial structure, while the Repeated Prisoner's Dilemma software and the Asymmetric Games software model uncorrelated play. [Details...]

5. Normal Form Game Applet

This applet allows you to create a two-player normal-form (simultaneous move) game with up to four strategies for each player. After you enter the payoffs, the applet solves the game, finding all pure-strategy Nash equilbria (and a unique mixed-strategy equilbrium, if one exists, for two-by-two games). [Details...]
