To overcome the shortcoming that the collision detection method based on three-dimension model only depends on the shortest distance between components to determine collision, a novel collision detection method for manipulators is proposed to indicate how dangerous the current movement of the robot are to the surrounding objects. The method more comprehensively considers the effect of the shortest...
there exist many problems in intrusion detection system such as large number of data volume and features, data redundancy and so on, which seriously affected the efficiency of the assessment. In this paper, we propose an approach called EFSA-CP to intrusion detection based on Cloud model and improved multi-objective Particle Swarm Optimization. The algorithm evaluates the characteristics of the attribute...
Particle swarm optimization is usually random, which leads to random distribution of search quality and search speed. So the general improved particle swarm optimization is difficult to meet fast optimization needs of some actual engineering. Stocks in the key generation of PSO algorithm generated by uniform design method can make particles in the population maintain a better uniform distribution...
A computer-aided method for architectural shape design was developed based on fractal algorithm. This method is creative, intelligent and automatic. Fractal algorithm applied here generates fractal dust as the data of unorganized points. Then the idea of surface reconstruction is borrowed in the construction of surface walls. In the process of surface reconstruction, the Power Crust algorithm has...
This paper presents a novel tutoring system. A multi-agent system architecture offers a promising framework for dynamically managing teaching agents in a distributed environment which uses computational approach to producing 3D images for computational intelligence (CI) course teaching. One teaching example is introduced for showing the advantage of the system. It uses complex function expressions...
Many applications can be formalized as dynamic problems and their main goals are to track the moving optimum. Many algorithms that address efficiently static problems, fail when applied to dynamic problems due to their inability to adapt and respond to changes in the environment. A different topology multi-swarm PSO is proposed to deal with problems in dynamic environment. The proposed algorithm integrates...
On the basis of in-depth study of the existing data mining algorithms, according to the disadvantages of them in relational databases, in this paper a new data mining algorithm based on association rules is presented. The algorithm can avoid redundant rules as far as possible, and the experimental results show that the performance of the algorithm can be obviously improved when compared with the existing...
Based on the modified co-evolutionary genetic algorithm, the signal timing of the urban single-point T intersection was optimized. In order to solve this problem, the shortest average delay was taken as objective, and the intersection geometry shape and prohibition of traffic flow conflicts were taken as restrictions. Simulation experiments show that the optimization signal phase figure results are...
