Outline of Annual Research Achievements

An evolutionary algorithm based on agent models and applied it to the modification of some finite element models of large structures have been successfully developed, which was reported by the Fellow. The algorithm obtained has relatively high computational efficiency and accuracy.

Current Status of Research Progress

2: Research has progressed on the whole more than it was originally planned.
