This paper describes efficiency of introducing a modification method that we proposed into a system for deriving diverse solutions. Moreover, a guideline of system parameter is proposed so as to utilize the effect that the modification method brings. Based on the concept of emergent design, the system for deriving diverse solutions can derive diverse and novel design solutions. However, most of the solution candidates that have novel shapes are inapplicable as solutions because of their low mechanical characteristics. For this reason, we have proposed a modification method by increasing and decreasing elements to reinforce the solution candidates. Setting local rules for modification, the method can reinforce the solution candidates without loss of their diversity. Though, the effect of the modification method is not clear, and the guideline of system parameter is not provided. Therefore, we make the effect of the modification method clear by comparing the solutions derived by the system with and without the modification method. Moreover, we provide a parameter guideline of system to effectively utilize the modification method.
