摘要:The authors propose approximate algorithms for solving the problem of the minimal vertex cover of arbitrary graphs and the problem of minimal cover on the basis of their reduction, respectively, to the problems of quadratic and nonlinear Boolean programming, their specificity allowing to construct algorithms with time complexity not exceeding O (mn2), where in the case of solving the problem of minimal vertex cover of arbitrary graphs n is the number of vertices in the graph, m is the number of edges in the graph, and in the case of solving the problem of minimal cover n is the number of columns in the Boolean matrix, m is the number of rows in Boolean matrix.
