  • 水位的最优发电效益
    说明:  本程序旨在计算在整个调节时段的初末水位已知的情况下(水位均为170米),从后往前计算出每个阶段的各个水位到最后阶段的最优发电效益,逐步向前递推找出最大年发电效益,从而找到最优化的路径放入到矩阵LJ中,本程序未考虑防洪限制。(The purpose of this procedure is to calculate the optimal power generation benefit for each stage from the rear to the final stage (the water level is 170m) in the case where the initial water level of the whole adjustment period is known (the water level is 170m), and the maximum annual power generation benefit can be found gradually forward. In order to find the optimized path into the matrix lj, the procedure does not take into account the flood control limitation.)

  • Pso
    模拟一群鸟捕食的情景,从而达到优化目标函数的目的,这就是粒子群算法!起初在可行的空间中随机的产生一群粒子,然后让每个粒子开始在虚拟的空间中向四面八方飞翔,并且每个粒子都记下他们飞过的适应值(也就是目标优化函数)最高的点,而且整个粒子群有一个最高适应值个体,这样,粒子在飞翔的时候尽量朝向自己曾飞过的最好的点和集体的最好的点。最后达到收敛到近似最优点的目的。 (Simulation of a group of birds preying on the scene, so as to achieve the purpose of optimizing the objective function, that is, PSO! At first, where feasible, have a space in a group of random particles, and then let the beginning of each particle in a virtual space to fly in all directions, and each particle they have in mind over the fitness value (that is objective optimization function) the highest point , and the whole particle swarm adaptation has a maximum value of the individual, so that particles in the fly when he had flown as far as possible towards the best point and collective best point. Finally reaching the merits of convergence to approximate most purposes.)

  • comfac
    comfac算法是三线性模型常见的数据检测方法。它首先将三线性数据通过tucker3模型压缩,然后通过最小二乘的方法不断更新数据,直到收敛,得到估计值( The algorithm works by first compressing the data using a Tucker3 models. Subsequently the PARAFAC model is fitted to the compressed array, either initialized with DTLD (~ESPRIT) or with PARAFAC-ALS. The solution is de-compressed to the original space, and a few safe-guard PARAFAC-ALS steps are performed. Further optimization of this algorithm is possible, e.g. if the data are very large, if the profiles are very correlated or if the noise is huge. This 、 has not been pursued here, in order to have a generally applicable algorithm)
