DYNAMO 3

 

Dynamo 3 is for single-population 3 strategy games. In this page, Dynamo 3 is explained briefly with screenshots.

In this part of the program, we select the game we want to analyze and give names to strategies. In this example, this is coordination game with 1, 2, and 3 as strategy names. Also we have an option to tell the program whether it should try to find Nash equilibria of the game, i.e. findnashequilibira=1 for yes.

Here we choose the dynamic we are interested in and tell the program whether it should try to find the rest points of the dynamic. Then we choose a contour function if we want our phase diagram to be drawn on top of a contour plot. As we see in the next screenshot, we have an option to include or exclude the contourplot, i.e. includecontourplot=1 for yes.

Here we choose the initial conditions for the dynamic. There are three preset initial conditions but you can choose any initial condition you want. The way how to do it is explained in "Instruction for "manual" specifications of sloution trajectories."

That's it, then we select outermost bracket, as in this screenshot, then hit the "shift+enter" or "enter" on the number pad of the keyboard. (When we open the file first time, Mathematica will ask whether we want to automatically evaluate all the initialization cells, we should say yes to this.) The following screenshots are output of this example.
