A dynamic clustering algorithm based on hybrid particle swarm-ant colony optimization (PS-ACO) algorithm is presented in the paper. In the algorithm, the number of cluster is dynamic, ACO algorithm is modified by particle swarm optimization (PSO), both the external function and internal function are used to measure the quality evaluation for clustering. The optimal partition is fulfilled by improved...
Based on the analysis of the first-fit arithmetic and dynamic equidimension memory allocation arithmetic, this paper proposes a new solution of dynamic memory management applied in embedded system. With the appending of dynamic equidimension memory table in the first-fit arithmetic, time spent in releasing the memory blocks is no longer dependent on the length of the allocated linked table. Meanwhile...
