Cooperative Coevolution (CC) was introduced into evolutionary algorithms as a promising framework for tackling large scale optimization problems through a divide-and-conquer strategy. A number of decomposition methods to identify interacting variables have been proposed to construct subcomponents of a large scale problem, but if the variables are all non-separable, all the CC-based algorithms of decomposition...
Aiming at the problem of intelligent path guidance in the parking lot, an improved Particle Swarm Optimization Algorithm(PSO) is proposed in this paper to find the optimal path. In order to overcome the shortcomings that standard PSO traps into local optima easily and improve the convergence speed of algorithm, the concept of GA and Multi-thread Technology are introduced. The experiment results show...
Fourth party logistics (4PL) was widely accepted by many companies nowadays. As one of the most important aspects in 4PL, the fourth party logistics routing problems (4PLRP) is very difficult to solve. Many intelligent methods has been used to solve the 4PLRP. Genetic algorithm (GA) is one fo such intelligent methods. Based on previous research, GA can work efficiently on small-scale 4PLRP. However,...
