http://web.mit.edu/6.251/www/lectnotes/10-23-lect.pdf WebApr 7, 2024 · I am attempting to solve a linear program via Dantzig-Wolfe decomposition. It is the first time I implement this method. Before the pricing iterations start, I need to provide an initial set of columns to the Restricted Master Problem. I know I can probably just feed a number of random columns initially. However, is there a smarter way of doing it?

Dantzig–Wolfe decomposition The Dantzig–Wolfe approach is an application of a decomposition principle: one chooses to solve a large number of smaller size, typically well-structured, subproblems instead of solving the original prob-lem whose size and complexity are beyond what can be solved within a reasonable amount of time. gpt 4 searchWebView ISYE6669_Homework11.pdf from APM 462 at University of Toronto.
