the paper improved the coding mode and repaired the radial pattern networks, so breeds out the infeasible solution reasonably, tails off the search space and boosts the procedure's calculating speed.
during searching process the self-adaptive penalty function can effectively utilize the available information in infeasible solution and appropriately punish the infeasible solution.
when genetic algorithm (ga) is used to solve the problems of distribution network reconfiguration, the infeasible solution will become a difficult problem.
