= Reactive strategy
{synonym}
A <reactive strategy> cooperates with <probability> $p$ after the opponent cooperated and <probability> $q$ after the opponent defected. It ignores its own previous action. <Independent> behavioural randomization gives a four-state joint-action <Markov chain>. The reduced marginal recurrences depend on the prescribed initial action distribution.
