Improved Firefly Algorithm: A Novel Method for Optimal Operation of Thermal Generating Units

“…The best can see that the proposed method can obtain less cost than FA, Lamda, and HM methods in [3] and [26] but slightly higher than cost of CSA and ICSA in [16]. The deviation implies that the proposed method is more effective than lambda, HM, and BBOA, but it is not less effective than methods in [16]. Besides, the proposed method has used much less N FES than other ones including FA.…”

“…For some optimization algorithms possessing two new solution generations such as CSA [15] and ICSA [16], ω is 2 while for others possessing one new solution generation like PSO [11] and DE [11], ω is only 1. For the proposed IFA, there is only one new solution generation in each iteration; thus, ω is also equal to 1.…”

“…The obtained results from the proposed method and other compared methods are given in Table 8. It is obviously seen that ICSA [16] has the best optimal solution; however, the confirmation of a valid solution is not done for ICSA because there was no optimal solution reported for the case in [16]. In comparison with mean cost and maximum cost of other ones, the proposed method has higher values because we run the proposed method with N FES of 1000 while others were run by a very high value.…”

“…where the limits related to dependent variables are determined by where PF is penalty factor used to amplify the violation of the dependent variable [16].…”

“…The comparisons of search speed have not been carried out. The performance of cuckoo search algorithm (CSA) [14,15] and improved cuckoo search algorithm (ICSA) [16] have been shown clearly since different types of constraints were considered and wide comparisons were implemented. However, the speed comparisons have been made only via execution time, leading to not good comparison criteria for conclusion.…”
