Abstract
We developed a dynamic production system of virtual flowerbeds using an interactive genetic algorithm on the Web. The initial population was consisted of 100 virtual flowerbeds. User selected about 10 flowerbeds as candidate parents. Next generation with 60 or 100 flowerbeds was produced by mating with each other in candidate parents and so on. Three ways of mating was used in this system, that is, 1) Two-point crossover, 2) Uniform crossover, 3) Crossover to preserve plant structure. 25 students used this system up to 7th generation. And the experiment of four-fold choices at a later date showed that the evolutional system produce more preferable flowerbeds than flowerbeds produced by manually. Furthermore, a MDS analysis using flowerbeds' hue components implied that there are no cluster structure and individual's preference is different respectively.
