EvoDyn-3s generates phase portraits of evolutionary dynamics, as well as data for the analysis of their
equilibria. The considered evolutionary dynamics are ordinary differential equations based on adaptive
processes taking place in a population of players who are randomly and repeatedly matched in couples to
play a 2-player symmetric normal-form game with three strategies. EvoDyn-3s calculates the rest points of
the dynamics using exact arithmetic, and represents them. It also provides the eigenvalues of the Jacobian
of the dynamics at the isolated rest points, which are useful to evaluate their local stability. The user only
needs to specify the 3 × 3 payoff matrix of the game and choose the dynamics.
