An effective path tracking control algorithm with speed adjustment is proposed. Traditional algorithms only use kinematic characteristics and take no consideration of dynamic restrains. Besides, most of the earlier studies on steering control assume that the longitudinal speed is constant, which is not reasonable. In this paper, we use an improved CLA with a PID controller for tight path tracking,...
In wireless sensor network, saving energy of sensor node for long circle life is important. In this paper, dynamic cluster based algorithm was proposed. The algorithm wake up or slept the sensing nodes though predicting the moving track of the target, reduce the number of tracking nodes to minimize network energy consumption. Selecting the optimal nodes to conduct the tracking task along the predicted...
The collection vehicle routing problems with intermediate facilities (CVRP-IF) is actually belong to a well-known generalization of VRP, the Multi-Depot Vehicle Routing Problem with Inter-Depot Routes (MDVRPI), which is a combinatorial optimization problem and holds a central place in reverse logistics management, such as waste collection management. This paper presents an improved multiple ant colony...
The paper analyzes the characteristics of ??Data Structure?? course, then starts from the teaching practice, carries through helpful exploration in following ways, such as teaching content, teaching methods etc. According to the experimental results, the method proposed by this paper can make an analogy to living examples for abstract concepts so as to improve the teaching quality and teaching effect.
In order to improve the dynamic and scalability of grid, the paper adopts the way fusing P2P and Grid organically, which resolves the issue that the node can join randomly and the resource-sharing can be dynamic in gird. This paper builds a resource architecture model based on P2PGrid and proposes a resource discovery algorithm fusing DHT and ant colony algorithm. This algorithm can accurately and...
A new filtering algorithm - PSO-PF was proposed for nonlinear dynamic systems. Basing on the concept of re-sampling, particles with bigger weights should be re-sampled more time, and in the PSO-PF, after calculating the weight of particles, some particles will join in the refining process, which means that these particles will move to the region with higher weights. This process can be regarded as...
According to rules of ants looking for food and immune genetic thought, an ant colony genetic algorithm is proposed based on immune mechanism. In precondition of keeping characteristics of the ant colony algorithm for global optimization and getting rationality of solutions in finite time, by introducing immune mechanism, the diversity of individuals can be assured and the phenomenon of long searching...
