According to research the concept of the genetic algorithm and multidimensional item response theory, using the method o genetic algorithm, this paper propose basic principle of estimation of multidimensional item response, theory model in person ability, changes and take the place of the calculation procedure, and gives the program design method.
An improved genetic algorithm for fuzzy programming problems with triangular fuzzy variables is proposed in this paper. The decentralization degree of fuzzy numbers is defined, and the way of coding triangular fuzzy number on [0, 1] is built. So we can limit the type of fuzzy numbers, increase the convergence property of algorithm, and make the fuzzy information processing more reasonable. Based on...
