LU
- In linear algebra, LU decomposition (also called LU factorization) is a matrix decomposition which writes a matrix as the product of a lower triangular matrix and an upper triangular matrix. The product sometimes includes a permutation matrix as well

Knapsack
- 算法设计与分析中背包问题。 首先将最优解矩阵的第一行和第一列均赋值为0；然后从上至下、从左至右依次计算m[i][j]的值，如果第i个物品 的重量大于j的值，即第i个物品不放入背包中，则将m[i][j]赋值为m[i-1][j]，否则取第i个物品放入背包和不放入背 包所得价值的最大值；最后从后往前计算最优解向量的值，如果m[i][j]=m[i-1][j]，则将x[i]赋值为0，否则将x[i] 赋值为1，并将j减去第i个物品的重量。-The knapsack problem al
