Bare bones particle swarm optimization (BBPSO) algorithm, a swarm intelligence algorithm, is famous for its easy applying and parameter-free. That is why its principles and applications have been studied by a IoT of scholars in recent years. However, quickly losing the diversity of the swarm still causes the premature convergence in the iteration process. Hence, a pair-wise bare bones particle swarm...
As we all known, autonomous navigation system is the basic of AUV movement, besides, accurate position estimation and reliable measurement are the keys of it. In order to avoid accumulating position errors in the long voyage by using navigation algorithm, we can depend on GPS. Due to the influence of diving and floating process, GPS data would slip. The slips affect the accuracy of navigation seriously...
In this paper, it is just doing a preliminary exploration to the multi-antenna array. The immune algorithm is used to achieve different directions for beam-forming and even pattern scanning. The array switches are loaded among the antenna arrays. The feed states and the switches among the arrays are controlled by using immune algorithm. Producing a particular orientation antenna pattern is regarded...
PSO Algorithm can search the extreme point of the complex objective function more effectively in contrast to tradition optimization algorithm. Based on PSO algorithm and geometric implication of the reliability index, a global optimal method is put forward to calculate the reliability index. In recently years, multi-pile composite foundation is widely used. The classification and the computation methods...
