This paper simplifies the algorithm of searching for the even alternating path that contains a maximal element using the minimal weighted k-matching theorem and intercept graph. A program for solving the maximal efficiency assignment problem was compiled. As a case study, the program was used to solve the assignment problem of water piping repair in the case of a large number of companies and broken pipes, and the validity of the program was verified.展开更多

It runs in O(logn) time with O(m/log+n+n) processors on an EREW PRAM for a class of graph set Ⅱ, where n=V, m = E and Ⅱ includes at leut (i) planar graphs; (ii) graphs of bounded genus; and (iii) graphs of bounded maximum degree and so on. Our algorithm improves the previoualy known best algoritbms by a factor of logn in the time complexity with linear number of processors on EREW PRAMs when the input is limited to Ⅱ.展开更多
