::the focal player adopts the best strategy among the players of the sampled reference/model group and keeps it's strategy if no one is performing better. This is a fully deterministic update rule. In special situations, i.e. in the case of ties, two additional rules are required to preserve the determinsitc updating. (i) if a reference player has the same score as the focal player then the focal player keeps it's strategy. (ii) if there are more than two strategies and two reference players with different strategies have a higher score than the focal player then the focal player adopts a strategy in a cyclic fashion depending on its current strategy. For example in the voluntary public goods game there are the three strategic types cooperate, defect and loner. A cooperating focal player with defecting and loner reference players that perform equally well but better than the cooperator, switches to the defector strategy. Similarly, a defector switches to loner and a loner to cooperator. This reflects the underlying cyclic dominance of the three strategies. It is important to note that these additional rules can always be avoided by choosing non-degenerate payoff parameters, i.e. parameters where the payoffs of different strategic types always differ.
