“…For encoding of the chromosomes, we use the encoding scheme proposed by Falkenauer [23] and Landa-Torres et al [38]. This encoding scheme is carried out by splitting each individual candidate in two parts: first, an assignment part in which the sentences are encoded.…”

“…Landa‐Torres et al. () put forward two new evolutionary algorithms based on genetic algorithms and harmony search approach. A grouping encoding procedure is introduced within both algorithms to guide the search and a unique local search based on swapping approach is applied to improve the solutions.…”

“…The methods based on genetic algorithms include a GA for capacitated PMP with a domain specific crossover (based on so-called exchange vectors) and mutation (heuristic hypermutation) [1], a mutation-less GA with greedy solution optimization [4], a GA with fixed-length subset encoding and domain specific heuristics [7], a GA with cut-and-paste crossover operator and hybrid local search [2], and a multiobjective [8] and grouping [9] GA variants. A common property of these approaches is the use of customized genetic operators, problem-specific local search, or heuristic solution optimization steps.…”
