To fur her s udy how he individual learning behavior and memory size influence he coopera ors, hree he erogonous ne works are es ablished. On he basis of agen- based compu a ional experimen s, he ver exes of ne w ork are regarded as he bounded- ra ionali y individual, and he fi ness func ion and evolu ion of individual s ra egies and learning behavior are also cons ruc ed . The resul s show ha pref eren ial learning rule improves he coopera ion level in BA scale-free ne w ork while reduces he regular ne w orks . And in his environmen , memory size changes he coopera ion level in all he ne w orks grea ly, while has li le impac when individual adop random selec ion learning rule. Besides, he increase of he group size makes he coopera ion level in BA scale-free ne w ork higher while i decreases he propor ion o
