As to the problem that it is difficult to estimate the parameters of Weibull mixtures accurately, a new parameter estimation method for Weibull mixtures based on the improved cuckoo search algorithm (CSA) is proposed. The optimization model, which is solved by the improved CSA, is established based on the idea of minimizing the residual sum of squares (RSS). The algorithmic improvement has three schemes...
Never Stop is an intelligent transportation system with sensor to control the traffic lights at intersection automatically. It utilizes fuzzy control method and genetic algorithm to adjust the waiting time for the traffic lights, consequently the average waiting time can be significantly reduced. A prototype system has been implemented at an EBox-II terminal device, running the fuzzy control and genetic...
This paper suggests one method to process images registration to promote time and precise combined gradient mutation information with improved genetic algorithm. Adaptive probabilities of the crossover and the mutation are adopted to prevent the process from falling into a local maximum. Combination of the mutual information strategy with adaptive probabilities of GA accelerates convergence of the...
Support Vector Machine (SVM) had excellent learning, regression ability and generalization ability, which used structural risk minimization based on smaller sample. The parameters of SVM have important effect to its performance. For this reason the parameters selection is the very important research content of the SVM. The traditional parameter selection method is time-consuming and difficult to obtain...
An improved algorithm of motion estimation is proposed based on H.264 coding standard in this paper. The basic principle of motion estimated is analyzed at first. Then the improved algorithm is designed. This algorithm makes improvements in selection of muti-reference frames, initial point of searching and process of searching. Especially an improved genetic algorithm is adopted in process of searching,...
The purpose of this paper is to search for the optimal connection of power transmission lines with underground power cables for a newly constructed substation to reduce the magnetic flux density around it. The genetic algorithm method is employed for solving the problem of optimization mentioned above to get a best connection. With the optimal connection, the magnetic flux density can be reduced effectively...
In this paper we study a new type of transshipment problem, the flows through the crossdock are constrained by fixed transportation schedules and any cargos delayed at the last moment of the time horizon of the problem will incur relative high inventory penalty cost. The problem is known to be NP-complete in the strong sense. We therefore focus on developing efficient heuristics. Based on the problem...
