Aiming at neural network structure designing problems, a new hybrid pruning algorithm was put forward. The algorithm consists of three steps. Firstly, it uses cooperative co-evolutionary genetic algorithm (CCGA) and back propagation algorithm (BP) to optimize the number of neural nodes and the weight values; Secondly, it calculates the significance of the hidden layer neurons; Thirdly, in order to...
This paper establishes the spatial kinematic model of the composite six-wheeled-legged robot according to its spatial motion, and simplifies the special motion postures so as to do the motion planning [1]. Furthermore, taking the slope obstacle as a typical example, it makes the analysis for the postures in the process of crossing the obstacle and optimizes the key postures in order to improve its...
