“…29 This case like case B is composed of 2 typical nonconvex ELD problems: type 1, an ELD problem considering only POZ constraint, and type 2, an ELD problem with considering both POZ and ramp rate limits. The results obtained for this case using CFA algorithm and also other reported algorithms in the literature such as CSO (civilized swarm optimization), 63 HBMO, 59 CIHBMO, 59 KHA-IV, 122 TL-QCP, 6 FAPSO, 41 CSA, 95 and NAPSO 41 for type 1, and PSO, 30 SOH-PSO, 30 GA, 30 MsEBBO/mut, 93 MsEBBO, 93 PSO-SIF, 38 MDE, 31 GAAPI, 25 FA, 88 CCPSO, 39 BFO, 61 NCS, 20 APSO, 47 CPSO, 36 ABC, 84 EPSO, 49 IA_EDP, 138 GABC, 82 EMA, 128 SGA, 14 and TLBO 118 for type 2 are listed in the Tables 13 and 14. It is clear from Tables 13 and 14 that the obtained results of min cost, mean cost, max cost, and SD values via the CFA algorithm are lower and more efficient compared with all the other algorithms.…”
