The industrial structure of the cities has undergone great changes, while the population is also in a large number of flows, which undoubtedly makes Chinese urban transportation construction and management face new standards and challenges. We proposed using immune algorithm to solve the transportation planning problems in this paper to shorten the total length of transmission network and transportation...
This paper presents a modified harmony search (MHS) algorithm for solving 0-1 knapsack problems. MHS employs position update strategy for generating new solution vectors that enhances accuracy and convergence rate of harmony search (HS) algorithm. Besides, the harmony memory consideration rate (HMCR) is dynamically adapted to the changing of objective function value in the current harmony memory....
The problem of resource allocation in multiuser OFDM system is a combinatorial optimization problem, difficult to solve in polynomial time. For the sake of reducing complexity, it can be solved either by relaxing constraints and making use of linear algorithms or by metaheuristic methods. In this paper, ant colony optimization, a typical algorithm of metaheuristic methods, is applied to solve the...
