一种改进的萤火虫算法解决动态0-1背包问题。经过测试，算法就有良好的性能。(Firefly Algorithm (FA), Genetic Algorithm (GA) and Differential Evolution (DE) have been widely used for static optimization problems, but the applications of those algorithms in dynamic environments are relatively lacking. In the present study, an effective FA introducing diversity with partial random restarts and with an adaptive move procedure is developed and proposed for solving dynamic multidimensional knapsack problems. To the best of our knowledge this paper constitutes the first study on the performance of FA on a dynamic combinatorial problem. In order to uate the performance of the proposed algorithm the same problem is also modeled and solved by GA, DE and original FA. Based on the computational results and convergence capabilities we concluded that improved FA is a very powerful algorithm for solving the multidimensional knapsack problems for both static and dynamic environments.)

小波工程主要包括一两部分：一、连续小波分析的应用，二、离散小波分析的应用。下面分两个部分分别说明这两个程序的分析结果： 一、连续小波分析： 所用信号为自己构造的三角波和正弦波叠加的信号：s=(-1).^(floor(n/50)+1).*(mod(n,50)-25)*2-(-1).^(floor(n/17)+1).*(mod(n,17)-8.5)*3+1*cos(n/2)*10。其中第一项(-1).^(floor(n/50)+1).*(mod(n,50)-25)*2为一周期为100的锯齿波，第二项-(-1).^(floor(n/17)+1).*(mod(n,17)-8.5)*3为一周期为34的锯波，第三项为一周期为4*pi正(余)弦波。另外叠加了一幅度为5的噪音信号。 程序包包含程序与说明文档。(Wavelet works mainly consists of two parts: first, the application of continuous wavelet analysis, II, Discrete Wavelet Analysis.)
