It is shown the efficiency of a hybrid solution by combining the optimization power of evolutionary algorithms and at the same time the efficiency of reinforcement learning in real-time and on-line situations. Experimental results concerning the navigation of a L-shaped robot in a cluttered environment with unknown obstacles are also presented. In such environments there appear real-time and on-line constraints well-suited to RL algorithms and, at the same time, there exists an extremely high dimension of the state space usually unpractical for RL algorithms but well-suited to evolutionary algorithms. The experimental results confirm the validity of the hybrid approach to solve hard real-time, on-line and high dimensional robot motion planning and control problems, where the RL approach shows some difficulties.}, identifier = {05718885}, }
