Chaos Quantum-Behaved Cat Swarm Optimization Algorithm and Its Application in the PV MPPT. [PDF]
Comput Intell Neurosci, 2017 Cat Swarm Optimization (CSO) algorithm was put forward in 2006. Despite a faster convergence speed compared with Particle Swarm Optimization (PSO) algorithm, the application of CSO is greatly limited by the drawback of “premature convergence,” that is, the possibility of trapping in local optimum when dealing with nonlinear optimization problem with a ...
