【Abstract】 To make human-computer interaction more effective, the human-computer interaction technique for human-computer interactive genetic algorithm (HCIGA) is researched. Two interface tools and their application methods are presented: the convergence diagram of the best and average fitness against generations, and the histogram of individuals′ distribution versus fitness compared with current optimum individual. The tools display the macro- and micro-state of the algorithm on the fly, and figure out when and how to add the artificial individuals into the population or to adjust the operators. Therefore, the merits of both human and computer can be developed effectively. On layout design of printed circuit board (PCB), HCIGA with the proposed interface demonstrates that it is superior to both SGA and HCIGA in precision, and it is superior to HCIGA but is inferior to SGA in effectiveness.更多还原
