Matrix-chainmultiplication Matrix-chainmultiplication 问题描述 Input:{p0, p1 ,... , p n}. a chain {A1, A2,..., A n} of n matrices for i = 1, 2,...,n , matrix A i has dimension p i-1 * p i.值得注意的该问题的输⼊定义及其巧妙，不仅定义了矩阵的⾏以及列，还说明了它们是...
Matrix chain multiplication is one of the classic optimization problems in computer science. For a given sequence \\(A_{1}\\), \\(A_{2},\\ldots ,A_{n}\\) of matrices, we need to compute the product of these matrices using the minimum number of scalar multiplications on a single ...
# 矩阵链乘 Matrix Chain Multiplication ## 题面翻译 ## 矩阵链乘 ### 题目描述 假设你必须评估一种表达形如 A*B*C*D*E,其中 A,B,C,D,E是矩阵。既然矩阵乘法是关联的,那么乘法的顺序是任意的。然而,链乘的元素数量必须由你选择的赋值顺序决定。 例如,A,B,C分别是 50 * 10 ,10 * 20...
Matrix multiplication problem is a typical example of dynamical programming. Suppose you have to evaluate an expression like A*B*C*D*E where A,B,C,D and E arematrices. Since matrix multiplication is associative, the order in which multiplications areperformed is arbitrary. However, the number ...

Hi @willow-ahrens @kylebd99, I wanted to discuss a bit Matrix Chain Multiplication Python example that I'm working on. The Python implementation relies on lazy indexing, as tensordot is slow for other examples, like SDDMM. Here's Python ...

UVA - 442 Matrix Chain Multiplication 双端队列 题目大意:给出n个矩阵和表达式,问该表达式是否正确,如果计算正确,输出计算了多少次 解题思路:双端队列,遇到右括号时弹出后面的两个矩阵进行乘法,相乘时要注意顺序,是第二个出队列的乘上第一个出队列的。
