In e-learning environment, computer-aided test-sheet composition play an important role in computer-aided testing systems. To meet the needs of multiple assessment criteria, a new test-sheet construction model was proposed. Based on the proposed model, a discrete differential evolution algorithm with effective coding strategy was designed to generate high quality test-sheets for computer-aided testing...
Resource allocation in grid environment is a complex undertaking due to the heterogeneity and dynamic nature aroused by wide area sharing. To address the heterogeneous and computationally intractable problem of resource allocation optimization in grid, this paper presents an allocation algorithm for parallel tasks based on particle swarm optimization. The heterogeneity of grid user is tackled by introducing...
Target assignment of coordinated distributed multi-agent system is an important yet difficult task. Previous methods (e.g., neural network, genetic algorithm, ant colony algorithm, particle swarm optimization and auction algorithm) used to address this problem have proved to be either too slow or not stable as far as converging to the global optimum is concerned. To address this problem, a new algorithm...
