Spring 1999 semester:

Jean-Pierre Langlois was teaching a mathematics seminar (Math 500) on "Markov Processes, Decisions, and Evolution." The seminar covered topics on matrices and some of their applications to Markov chains, dynamical systems, and evolutionary game theory.

The seminar was part of a new collaboration between the Department of Mathematics at San Francisco State University and the Mathematical Sciences Research Institute (MSRI) in Berkeley. The project allows our Faculty and graduate students to participate in the programs run by MSRI. During the Spring 1999, MSRI had a program on random matrices. Part of the seminar was devoted to an introduction to that subject. Speakers from MSRI were invited to give talks here, at SFSU.

The lecture series was videotaped and translated into streaming video format. It can be accessed at the MSRI web site http://www.msri.org/

GamePlan is a Windows-based computer software package that was developped to design and solve a wide range of game models from the normal to the extensive forms, from perfect to imperfect and incomplete information and from one-shot to repeated and graph-based structures. The solution concept is a generic "perfect" equilibrium that reduces to the subgame perfect, the perfect Bayesian or the Markov perfect equilibrium, depending on the structure. The Nash equilibrium is only supported in the normal form.

You can download the version 3.7 installer here GamePlan 3.7

To learn how to use GamePlan you may use: User Manual

You may also watch this video that was developped for the earlier version 2.7: GamePlan Video

At installation you are automatically granted a 30 day license. How to obtain a (free) one year license is explained on pp. 2-3 of the user's manual.

GamePlan has been reviewed in the Economic Journal, Vol. 110, No. 461, February 2000, pp. F166-171.

Jean-Pierre Langlois often teaches game theory in mathematics (at SFSU) or in political science departments (at Georgetown University). His standard course uses the GamePlan software and simulations played in class by the students.

One of the most successful simulations is the Persian Gulf Missile Crisis inspired by the (real) Persian Gulf crisis and war between Iraq and the U.S.-led coalition in the early 1990's. One major difference is that Iraq is assumed to possess a few nuclear weapons. The simulation is designed with a high propensity for escalation and eventual nuclear conflict. The major challenge for the players is to achieve a negotiated settlement without resorting to nuclear attack or retaliation.

Students having played the crisis often express surprise at the outcome and a sense of powerlessness in controlling its motion.
