Tabu Search Traveling Salesman Problem

函数注册在Matlab和C++接口中起着重要的作用。在介绍函数注册作用的基础上，详细分析了函数注册的过程及应当注意的问题，并给出了一种实现函数注册的最简单的方法。用实例展示了函数注册的具体实现过程。 (registration function in Matlab and C interface plays an important role. In introducing the role of the registration function on the basis of a detailed analysis of the function of the registration process and should pay attention to the problem, and gives a registration function to achieve the most simple method. Examples demonstrate the function of the concrete realization of the registration process.)

说明：  　本文对变步长自适应滤波算法进行了讨论,建立了步长因子μ与误差信号e(n) 之间另一种新的非线性函数关系. 该函数比已有的sigmoid 函数简单,且在误差e(n)接近零处具有缓慢变化的特性,克服了Sigmoid 函数在 自适应稳态阶段步长调整过程中的不足. 由此函数本文得出了另一种新的变步长自适应滤波算法,并且分析了参数α,β的取值原则及对算法收敛性能的影响. 该算法有较好的收敛性能且计算量少. 计算机仿真结果与理论分析相一致,证实了该算法的收敛性能优于已有的算法.(In this paper, variable step adaptive filter algorithm to discuss the establishment of a step factor μ and the error signal e (n) between another new nonlinear function. The function has a sigmoid function than the simple and the error e (n) close to zero Department has a slow change in the characteristics of a Sigmoid function to overcome the steady-state phase in the adaptive step length adjustment during the process. this function, this paper gives another new variable step size adaptive filtering algorithms, and analysis of the parameters α, β the value principles and the convergence performance. The algorithm has better convergence performance easy to calculate. Simulation results and theoretical analysis, confirmed the convergence of the algorithm better performance than existing algorithms.)
