Detailed Description

Widget for forward simulating an equilibrium.

This widget is constructed by SGSolutionHandler when the user requests to simulate a particular equilibrium from the right-click context menu on one of the SGCustomPlot objects. This class constructs an SGSimulator object from the SGSolve library, and it also constructs plots and text edits for viewing the output of the simulation. The user can then input the number of periods for which to simulate the equilibrium. The widget will then use SGSimulator to run the simulation. The output is displayed in various formats. The first 200 periods of the simulation are displayed, along with the decomposition of all extremal equilibria into stage payoffs and a lottery over continuation equilibria. If there is more than one decomposition of the continuation value, one is selected arbitrarily. The widget also shows the distributions of tuples, states, actions, and average payoffs of the players over the course of the simulation.
