Creatures consist of rigid primitives, joints, and neural controller and these parameters are evolved with real number coded genetic algorithm. Creatures are evaluated in a virtual environment that implemented physical forces for achieving various simple tasks such as walking, pursuit toward a target, and evasion from obstacles. Acquired shapes of creatures are classified into 4 types according to a feature value named "number of branches". Experimental results showed that the creature has a specific number of branches obtained a high fitness.}, pages = {595--601}, title = {人工生物の形態進化における獲得形態の評価 -タスク難易度が及ぼす獲得形態への影響-}, volume = {82}, year = {2016} }
