Abstract: Multi-hole routing is a typical constrained combinational problem. Aimed at the problem of limitations of poor convergence and path shock, a method is proposed based on an improved cooperative co-evolution algorithm and the structure feature of hydraulic manifold blocks, according to the structure of hydraulic manifold block, an improved cooperative coevolution for optimization of holes routing is proposed. Firstly, the transfer strategy and rules of heuristic information are ameliorated to improve the process efficiency and the overall performance based on the premise of solving the problem of multi-hole connection. Then, the feasibility is testified through the simulation. Finally, the adaptive value is improved and compared with current results of inner holes routing of hydraulic manifold blocks, more satisfied results are obtained.
