抄録: Inspired by organism evolution, evolutionary algorithms have attracted research interests for several decades, and have been proved effective and efficient to solve optimization problems. For further enhancement, local search are introduced into evolution, imitating the biological fact that organism individuals change themselves to better fit the environment during their lifetime. In the context of evolutionary computation, Baldwinian evolution hybridizes global search through population-based evolution with local search through individual refinements. Refinement influences selection, however, unlike Lamarckian evolution, refined traits are not inherited by the offspring. In Baldwinian evolution, local search guides evolution in an indirect manner, termed "the Baldwin effect". Conventional studies revealed that Baldwinian learning can enhance search, however, there is still considerable work to be done to understand the mechanisms. This thesis investigates Baldwinian evolution's mechanisms in depth. By proposing the method of analyzing individual dynamics, we present some novel views. We find that the substantial inheritance in Baldwinian evolution is the potential to achieve high fitness through learning, that the realization of learning potential is influenced by inheritable and noninheritable factors in evolution, and that learning cost penalties inhibit learning intensity. Our results provide knowledge of Baldwinian evolution's mechanisms, and directions to possible applications.
