This method is a generalization of Mizuno, Todd and Ye's result. Although the search direction of this algorithm is the same as that of the path-following algorithm, the step size is determined as the minimum point of the potential function in the neighborhood. Therefore, the duality gap is reduced by a fixed positive constant at each step. Finally, the polynomial complexity O((2κ + 1 + max{κ, 1 over 4}M)nt)is attained when the problem satisfies a scaled Lipschitz condition, where t is a positive constant and M is defined in the condition.","PeriodicalId":189187,"journal":{"name":"Third International Workshop on Advanced Computational Intelligence","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121314223","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus intelligent game opponent can be made adaptive to match different player strategies and different player skills. Traditional difficulty adjustment setting the status of the opponent often fills players with a feeling of being cheated, which cannot perfectly satisfy the player. In this paper, we demonstrate that by adjusting the challenge level of opponents through Computational Intelligence (CI) approach including Monte Carlo Tree Search (MCTS) and Upper Confidence bound for Trees (UCT) algorithms, we can realize Dynamic Difficulty Adjustment (DDA) and make players' game experience more personalized. However, as one character of CI approach is computational intensiveness, it may only be practical for offline game. Compared to that, another proposed DDA approach: adaptive Artificial Neural Network (ANN) controlled opponents can extend dynamic difficulty application to online field.","PeriodicalId":189187,"journal":{"name":"Third International Workshop on Advanced Computational Intelligence","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126629316","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Reliability of analog circuits becomes more and more important for yield design. However, most state of the art researches are concentrated on analog circuit robust optimization and analog circuit fault detection. There are seldom any researches on analog circuit fault-tolerant design. This paper proposed an negatively-correlated evolution strategy to design fault-tolerant analog circuits. In the proposed strategy, the fault-tolerant circuit can be considered as an ensemble system. The system contains several child circuits. negatively-correlated evolution strategy automatically synthesizes these child circuits, and make sure the errors of each child circuits are negatively correlated to each other. The experimental result shows that, in most circumstances, the circuit with negative correlation redundancy has the best fault tolerant performance compared with the circuit with randomly generated redundancy. The the circuit with duplicated redundancy didn't has much improvement compared with single circuit. So, the proposed strategy is a beneficial idea towards robust and fault tolerant analog circuit design.","PeriodicalId":189187,"journal":{"name":"Third International Workshop on Advanced Computational Intelligence","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131357395","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
