“…It can be found out that the initial population includes a lot of tour paths, while this result in practical distribution is not reasonable and not realistic in distribution activities. For example, in K initial 1 = [9,3,9,11,7,17,14,8,9,3,3,1,2,4,1,13,1,17,11,16], path [9 3 9] is a tour path, which is not allowed in operation. Design pretreatment operator and deal with the repeated path and tour path in the path.…”
