In the original publication of the article, Fig. 6 was published incorrectly and has been corrected with as follows:
Incorrect diagram
Fig. 6 Chromosome representation for BMOPSOCD, BMOGWOCD and BMOWOCD
Revised diagram
Fig. 6 Continuous representation for BMOPSOCD, BMOGWOCD and BMOWOCD
Additionally, there were minor typographical errors in Sect. 4.2 related to Fig. 6 and have been corrected as below:
Incorrect Sect. 4.2:
4.2 Other algorithms
The proposed NSGA-II variants are compared with BMOPSOCD [state-of-the-art algorithm in the literature for WSLAP (Tan et al. 2021)] and multi-objective versions of GWO (Mirjalili et al. 2014) and whale optimizer (Oloieri and Diac 2021). BMOPSOCD is the best available metaheuristic for WSLAP, which has a novel chromosome encoding procedure to convert the real coding of PSO to binary encoding, as shown in Fig. 6, and a fixed-sized external archive to store the non-dominated solutions. The diversity among the population members is maintained using the crowding distance mechanism.
The pseudocodes used for coding the multi-objective versions of GWO and whale optimizer are similar to BMOPSOCD. These algorithms are also integrated with an external archive and use the crowding distance mechanism to maintain the population diversity. The chromosome encoding, initialization, and dominance criteria are also the same as BMOPSOCD. Therefore, we have used a similar naming convention as BMOPSOCD and named them ‘BMOGWOCD’ and ‘BMOWOCD’.
