To solve the problem that the ant colony algorithm is easy to fall into local optimal solutions in solving the shortest path problem, improvements on the classical ant colony algorithm are provided in three aspects. Firstly, direction guiding is utilized in the initial pheromone concentration to speed up the initial convergence; secondly, the idea of pheromone redistribution is added to the pheromone...
In this paper, a novel iterative algorithm for the joint diagonalization of a set of real symmetric matrices is presented. The approximate joint diagonalization of a set of matrices is an important approach in many blind source separations (BSS) applications. By applying the least-squares criterion, a classical nonlinear least-squares cost-function of the BSS problem is obtained. An explicit method...
This paper combines chaos operator with Immune Algorithm, and advances Chaos Immune Algorithm. In this algorithm, the ergodic property of chaos phenomenon was used to optimize the initial antibody population. Through the clone selection operator, mutation operator and recruited antibody, local optimums were avoided, so the global optimization was obtained. Through the algorithm performance analysis,...
