| Outline of Final Research Achievements |
We tackled four subthemes on knowledge based on human factors in evolutionary computation (EC) to increase the diversity of EC research: (1)knowledge on improving/developing EC algorithms, (2) knowledge to explain the validity of a searched out optimum solution to engineers, (3) knowledge to explain evaluation characteristics of an interactive EC user, and (4) knowledge to make an interactive EC user aware his/her own evaluation characteristics.
As its results, we obtained outcomes of: several devices for improving existing EC algorithms. a new EC algorithm and its analysis, a new niche method, new method of large-scale optimization adopting sparse modeling, a tool bridging an objective space and an design parameter space in multi-objective optimization, evaluation of proposed awareness support system, and others.

| Academic Significance and Societal Importance of the Research Achievements |
第1の学術的意義は，進化計算研究コミュニティでは稀な「人間要素を絡ませた知識」というキーワードの研究を行うことで，進化計算研究の多様性を示した点である．第2の学術的意義は，新進化計算アルゴリズムの提案と解析，新ニッチ手法の提案，sparse近似や球面集中現象にヒントを得た進化計算の戦略など，独自性が高い手法・アプローチを示した点である．
本研究は進化計算の基礎的位置付けであるが，ハイブリットロケットエンジンの設計や賃貸住宅データベースの検索という実社会の具体的タスクも取り扱っており，実用イメージを社会に与える点で意義がある．
