Fuzzy controllers are represented by if-then rules and thus can provide a user friendly and understandable knowledge representation. Evolutionary algorithms have been widely used for optimal design of fuzzy controllers. In this paper, we first present the state-of-art adaptive fuzzy control design using evolutionary algorithms and then attempt to enhance the performance of the simple genetic se...

this research presents a new application of the cloud theory-based simulated annealing algorithm to solve mixed model assembly line sequencing problems where line stoppage cost is expected to be optimized. this objective is highly significant in mixed model assembly line sequencing problems based on just-in-time production system. moreover, this type of problem is np-hard and solving this probl...

We report the occurrence of quenching and annealing in a version of the Minority Game (MG) in which the winning option is to join a given fraction of the population that is a free, external parameter. We compare this to the different dynamics of the Bar Attendance Model (BAM)where the updating of the attendance strategy makes use of all the available information about the system and quenching d...

多峰性の連続最適化問題にシミュレーテッドアニーリング (SA)を適用する場合,著者らがすでに 提案している最適な受理確率を目標とする適応的近傍を持つ SA(SA/AAN)が有効である.本論文 では,並列計算機を用いて組み合わせ最適化問題を解く場合に有効な並列アルゴリズムの 1つである 温度並列シミュレーテッドアニーリング (TPSA)に SA/AAN を組み込んだ手法を提案する.提案 手法は各プロセス (プロセッサ)が担当する各温度において,適応的な近傍拡大率を持つ近傍を用い て探索するため,関数のランドスケープに適応した探索が行うことが可能である.一方,TPSAは温 度スケジュールが不要であるという特徴がある.そのため本論文で提案する手法は,温度,近傍とも に関数のランドスケープに合わせ自律的な調節を行うことができるという優れた特徴を持つことがわ かった.3 つの代表的なテスト関数...

The influence of the atomic order on the martensitic transformation entropy change has been studied in a Ni-Mn-In-Co metamagnetic shape memory alloy through the evolution of the transformation temperatures under high-temperature quenching and post-quench annealing thermal treatments. It is confirmed that the entropy change evolves as a consequence of the variations on the degree of L21 atomic o...
