The traditional K-means clustering algorithm has the disadvantage of weakness in overall search, easily falling into local optimization, highly reliance on initial clustering center. Aiming at the drawback of falling into partial optimization, putting forward a modified K-means algorithm mixing GA and SA, which combined the advantages of global search ability of GA and local search, to avoid K-means algorithm to lost into local optimal solution. The results of simulation show that the performance of above-mentioned algorithm is better in the optimization capacity than before, and easier to get the global optimal solution. It is an effective algorithm.

Multi-Depot Vehicle routing problem is an NP-HARD problem. Because the genetic algorithm is easy premature convergence and search efficiency is not high, this paper established the defects of polymerization degree model, and based on this, this paper proposes an improved algorithm, this algorithm can change the mutation rate according to their own chromosome degree of polymerization size to avoid the prematurity of genetic algorithm, and improved genetic algorithm search efficiency. Through the contrast, the results showed that the algorithm has good search efficiency and stability, which demonstrates that the improved algorithm is effective and feasible for multi-depot vehicle routing problem.
