In this paper, we explicitly explore how to manipulate single qubits by one-rotation controls under various manipulation conditions. It is revealed that one can construct control Hamiltonian and adjust the control to manipulate quantum states. Furthermore, we comprehensively discuss how to optimize control magnitude in terms of a new kind of weighted time-energy performance. A comparison has been made among the optimal performances under different manipulation conditions. Three concrete examples indicate the feasibility and efficiency of this approach on optimal control of two-level quantum systems.

This paper presents an approach to solve the Vehicle Scheduling Problem(VSP). Taking into the actual connectivity of paths connected to the nodes, we establish a multi-objective mathematical model based on the path length and customer waiting time. A algorithm combining the A* algorithm for path searching with the Particle Swarm Optimization(PSO) for global exploration together, is applied to the multi-objective vehicle scheduling model. Some practical problems has been solved with good results by this approach.
The model for the energy consumption problem of the aluminum industrial production is established in this paper, and the energy consumption situation out of one ton of aluminum production is calculated. The threshold cluster analysis algorithm is a method of saving energy of the producing process. However, the choice of its distance threshold is somewhat random, so further work has been done to improve the algorithm's performance, that is calculating the distance threshold with a function of the maximum distance and the minimum distance between all of the energy consumption data. Through simulation experiments and comparative analysis, the fact that the improved algorithm performs better is shown. A better reasonable input can be found faster, and the energy saving of the aluminum industrial production is much more effective.
To the prolbems in the alumina ore-burden process,such as the uncertain factors,the heavy calculations,the difficulty of obtaining an optimal scheme,and the energy waste caused by the irrational structure of production,with the minimum of energy consumption as the objective function,consider the production experience,an optimal scheduling model of unified ore-burden in sintering and Bayer process is presented.Comsidering the existence of nonlinearity,multiple constraints and multi-objective,a hybrid particle algorithm with mutation parameter is proposed to get the optimum solution.Based on the scheduling method,the optimal scheduling software in the alumina ore-burden process is desingned and exploited.The computation results show that the optimal scheduling software can offer the best alumina ore-burden scheduling scheme,the minimum energy consumption can be obtained efficiently,and the distinct effect of application is obtained.

This paper presents an approach based on hybrid particle swarm optimization to solve weapon-target assignment (WTA) problem. The mathematical model of WTA problem is explained in detail. Then the idea of basic particle swarm optimization (PSO) is introduced. A hybrid PSO algorithm (HPSO) is structured by introducing the mutation operator and changing the inertia weight with the generation. The results of simulation indicate that this approach is effective to solve WTA problem.
In this paper, a multi-agent particle swarm optimization (MPSO) based on multi-agent system (MAS) and PSO was proposed for hybrid flow-shop scheduling problem (HFSP), and a random cycle topological structure is presented related to MPSO. In MAS, every particle represents an agent, and it can cooperate and compete with the agent around and do self-learning. Using these agent interactions and the evolution mechanism of PSO, MPSO can find the global optimum more accurately. The result of simulation proved that this algorithm has a higher searching efficiency and better optimal searching performance.
Traditional research on production scheduling in aluminum industry, aimed to certain production process, simply pursued the output as the highest aim, scheduled based on experience, so that the result of scheduling cannot reach the global optimization, and cannot realize production scheduling and resource allocation with the aim of optimal energy consumption, resulting in the waste of energy. Taken the minimal sum of energy consumption in production, transport and stock as objective function and integrated with enterprise’s experiences in production, the article establishes a model of virtual enterprise’s task scheduling in aluminum industry and a hybrid distributed particle swarm optimization (PSO) algorithm is proposed to solve the problem. Finally, simulation experiment is carried out using industrial data and the result shows the optimized scheduling method has obvious optimal effect on reducing scheduling time, optimizing allocation of resources and so on, and thus the energy saving and consumption reducing purpose are obtained.

This paper presents an approach based on constructing control Hamiltonians to steer qubit states. When three tunable control Hamiltonians are available, we can adjust the controls to transform two-level quantum systems from an arbitrary initial pure state to another arbitrary target pure state along the unique geodesic curve on Block sphere.

An example indicates the feasibility and efficiency of this approach on optimal control of two-level quantum systems.
