“…For the first experiment, the following algorithms were employed: two inertia weight PSO algorithms with different parametric settings (ω = 0.9 → 0.4, c 1 , c 2 = 2 and ω = 0.4, c 1 , c 2 = 2) and HIDMS-PSO (ω = 0.99 → 0.29, c 1 = 2.5 → 0.5, c 2 = 0.5 → 2.5) [7], metaheuristics ( the bat algorithm (BA) [12], grey wolf optimiser (GWO) [13], butterfly optimisation algorithm (BOA) [14], whale optimisation algorithm (WOA) [15], moth flame optimisation (MFO) [16], artificial bee colony (ABC) [17], invasive weed optimisation (IWO) [18], flower pollination algorithm (FPA) [19] and cuckoo search algorithm (CS) (p = 0.25) [20]). For the second and third experiments, we have employed the following PSO variants: genetic algorithm assisted HIDMS-PSO (GA-HIDMS-PSO) (ω = 0.99 → 0.29, c 1 = 2.5 → 0.5, c 2 = 0.5 → 2.5) [21], HIDMS-PSO with bio-inspired fission-fusion behaviour and a quorum decision mechanism (FFQ-HIDMS-PSO) (ω = 0.99 → 0.29, c 1 = 2.5 → 0.5, c 2 = 0.5 → 2.5) [22], standard HIDMS-PSO (ω = 0.99 → 0.29, c 1 = 2.5 → 0.5, c 2 = 0.5 → 2.5) [7], HPSO-TVAC [23], FDR-PSO [24], heterogeneous comprehensive learning and dynamic multiswarm PSO (HCLDMS-PSO) (ω = 0.99 → 0.29, c 1 = 2.5 → 0.5, c 2 = 0.5 → 2.5, pm = 0.1, V max = 0.5 * Range)) [25], heterogeneous comprehensive learning PSO (HCLPSO) [26], self-organizing hierarchical PSO with jumping time-varying acceleration coefficients (MNHPSO-JTAC) [27], χPSO (ring with neighborhood radius n r = 2, φ = 4.1, χ = 0 : 72984, c 1 , c 2 = 2.05) [28], bare bones PSO (BBPSO) [29], dynamic multi-swarm PSO (DMS-PSO) (ω = 0.729, c 1 , c 2 = 1.49445, V max = 0.5 * Range) [30], fully informed particle swarm optimizer (FIPS) [31], unified PSO (UPSO) [32] and comprehensive learning PSO (CLPSO) (ω = 0.9 → 0.2, c 1 , c 2 = 1.49445, V max = 0.2 * Range) [33] and SRPSO (ω = 1.05 → 0.5, c 1 , c 2 = 1.49445, V max = 0.06708 * Range) [34]. In the conducted experiments, the population of all baseline metaheuristics were set as 100, and the population of PSO variants (including the proposed algorithm) was set to 40 [7].…”
