The Community Question Answer (CQA) service is a typical forum of Web 2.0 that shares knowledge among people. There are thousands of questions that are posted and solved every day. Because of the various users of the CQA service, question search and ranking are the most important topics of research in the CQA portal. In this study, we addressed the problem of identifying questions as being hard or...
To solve the problems of job shop scheduling under uncertain information, the paper builds a rough constrained model which overcomes the defects of traditional methods which need pre-set authorized characteristics or amount described attributes, and proposes a new maximum entropy estimation of distribution algorithm to solve these complex problems. The simulation tests of Muth and Thompson's benchmark...
Estimation of Distribution Algorithms (EDAs) is new kinds of colony evolution algorithms. It produces its new generation by constructing probability distribution model through counting excellent information of individuals of present colony EDAs first, and then sampling the model. To solve the NP-Hard question as EDAs searching optimum network structure, a new Maximum Entropy Estimation of Distribution...
