Vector Evaluated Particle Swarm Optimization (VEPSO) has been successfully applied to various applications. However, the VEPSO actual performance is still uncertain. Hence, this paper will evaluate the VEPSO performance in term of convergence and diversity ability using Generalized Distance and Spread measurement respectively. Simulation with ZDT benchmark test problems show VEPSO is weak in solving...
This paper investigates the evolutionary dynamics of steady-state real-valued evolutionary algorithms (RVEAs) with more-than-one-element replacement theoretically, whereas most theoretical studies of RVEAs have considered single-or all-element replacement. The subject RVEAs are of interest because they appear in various fashions, such as real-coded genetic algorithms (RCGAs) and island RVEAs. The...
In this paper, we present a novel quantum-inspired genetic algorithm with expanded solution space. Based on the double chains quantum genetic algorithm (DCQGA), we have expanded the solution space by increasing the number of solution space transformation functions. And we propose a novel method for quantum rotation gate's update by using the sign function and the gradient of objective function. With...
