In this study, we examine what strategies survive under infinite group dynamics when players cause implementation errors in an iterated prisoner's dilemma. In the previous studies, the Win-Stay, Lose-Shift (WSLS) strategy, which is a representative strategy can be the most abundant in the presence of implementation errors among memory-one strategies. In contrast, we use replicator-mutator dynamics to examine the consequences in a strategy space represented by finite state automata within two states. As a result, we observe a Unilateral Defection, Mutual Defection (UDMD) strategy that behaves effectively when players cause implementation errors, and clarified the survival process.
