Estimation of traffic matrices, which provides critical input for network capacity planning and traffic engineering, will be contaminated by the dirty data created by troubles such us hardware/software/transmission. To solve this problem, a SNMP-data-self based sparse dirty data model and a sparse dirty data processing algorithm based on alternating projection are proposed here. The former occupies...
The known mathematical model for clustering problems is given in this paper. With the K-Means algorithm, the simulated annealing algorithm and a novel hybrid ant colony algorithm is integrated with the K-means algorithm to solve clustering problems. The advantages and shortages of K-Means algorithm, simulated annealing algorithm and the hybrid ant colony algorithm are then analyzed, so that effectiveness...
An Immune Genetic Algorithm (IGA) is used to solve weapon-target assignment problem (WTA). The used immune system serves as a local search mechanism for genetic algorithm. Besides, in our implementation, a new crossover operator is proposed to preserve good information contained in the chromosome. A comparison of the proposed algorithm with several existing search approaches shows that the IGA outperforms...
