Optimization algorithms continue to be vital in solving complex problems. Among these, the Cyclic Parthenogenesis Algorithm (CPA) draws inspiration from aphids' reproductive strategies, balancing solution exploitation and search space exploration. Proposed by Ali Kaveh and Zolghadr, CPA involves colonies of solutions, with mechanisms for both self-replication and paired reproduction. It organizes decisions within the colony and introduces migration between them for information exchange.

Implementing CPA involves creating several colonies, each having "female" and "male" individuals. The process includes using the C_AO_CPA class, which manages parameters like population size and colony count. The algorithm proceeds through initializing, moving, and revising solutions, incorporating factors such as scaling and flight probability.
