The list below describes only the few parameters related to specifying the evolutionary dynamics of two species, say hosts and mutualists, with payoffs solely based on inter-species interactions. Numerous other parameters are available to set population structures or update rules on the player as well as population level.
--payhost <a,b;c,d>
payoff matrix for the host species. This indicates the payoffs when cooperator or defector hosts interact with cooperator or defector mutualists. For example a cooperator host obtains b against a defecting mutualist. This is the complement to --paymutualist <a,b;c,d>.
--paymutualist <a,b;c,d>
payoff matrix for the mutualist species. This indicates the payoffs when cooperator or defector mutualists interact with cooperator or defector hosts. For example a defector mutualist obtains c against a cooperating mutualist. This is the complement to --paymutualist <a,b;c,d>.
