“…However, researches on EA representations for complex problems (Rothlauf, 2006) show that populations with feasible solutions have very slow convergence, since the unfeasible solutions dominated the evolutionary process with the increasing of the problem size. This phenomenon has been also verified in the PSP problem (Krasnogor et al, 1999;Cotta, 2003;Gabriel & Delbem, 2009). In order to solve the problem of unfeasible solutions, Gabriel & Delbem (2009) propose a new approach using AR and a conformation matrix (C M ).…”

“…Caso haja colisões (ou seja, caso n C (c) seja maior que 0), é atribuído 0 ao termo n H (c) (Gabriel and Delbem, 2009). Dessa maneira, evita-se calcular a aptidão para todos os indivíduos durante parte do processo evolutivo, e esses passam a ser classificados em dois grupos: os de fitness negativo (infactíveis) e os de fitness positivo (factíveis).…”

“…Experimentalmente, no entanto, pôde-se observar que a aptidão média da primeira geração é muito baixa, o que significa que todos os indivíduos apresentam colisões, ou seja, são infactíveis (Gabriel and Delbem, 2009). Essa observação motivou o desenvolvimento de um método para corrigir colisões e iniciar o processo de busca em regiões mais promissoras do espaço.…”
