平均因子分解法应用于正定矩阵
平均因子分解法,适用于正定矩阵First, let s recall the definition of the Cholesky decomposition: Given a symmetric positive definite square matrix X, the Cholesky decomposition of X is the factorization X=U U, where U is the square root matrix of X, and satisfies:
(1) U U = X
(2) U is upper triangular (that is, it has all zeros below the diagonal).
It seems that the assumption of positive definiteness is necessary. Actually, it is "positive definite" which guarantees the existence of such kind of decomposition. -Average factor decomposition method applied to positive definite matrix First, let s recall the definition of the Cholesky decomposition: Given a symmetric positive definite square matrix X, the Cholesky decomposition of X is the factorization X = UU, where U is the square root matrix of X, and satisfies: (1) UU = X (2) U is upper triangular (that is, it has all zeros below the diagonal).

C# TSP问题以及VRP问题
7、满足随机数大于交叉概率的进行交叉,双交叉点交叉法(已实现)8、初始种群中染色体用Floyd方法或扫描法(未实现,想等到收敛性有一定程度的保证后再采用扫描法)9、两点之间的距离是坐标间的直线距离,之后可以用直接输入的距离10、迭代次数不是很稳定,有时候会陷入死循环,停止调试,重新调试即可11、每点击一次重新运行,程序便从头计算一次,目前我自己遇到的最好结果是3辆车、20个点的情况下总路程105.4,最好染色体适应度0.09+12、约束条件是:车辆数量、载重量和里程数。超出载重量或里程数则换车,超出车已有车辆数量就惩罚。13、建立了解决VRP问题的类,需要时派生出不同的参数适应不同问题
