“…ELPSO is compared with conventional PSO (CPSO) [6], harmony search (HS) [31], genetic algorithm (GA) [32], firefly swarm optimisation (FSO) [33], gravitational search algorithm (GSA) [34], brainstorm optimisation (BSOA) [35] and artificial bee colony (ABC) [36]. Moreover, ELPSO will be compared with some modified variants of PSO and differential evolution (DE) including opposition-based DE (ODE) [37,38], competitive DE (CDE) [39], fixed inertia weight PSO (FIW-PSO), chaotic inertia weight PSO, random inertia weight PSO, time varying acceleration coefficient PSO (TVACPSO) and constricted Fig. 11.…”
