Dantzig-wolfe decomposition example
WebJan 24, 2024 · 7 Most descriptions of the Dantzig-Wolfe decomposition, I have seen end up with subproblems like this: min x j ∈ R n { ( π A j − c j) x j ∣ x j ∈ P j } WebBy looking at that general definition, I wonder if it is not, in general, the same process used by Dantzig and Wolfe with their decomposition technique: Divide: Accomplished by models with a special constraints structure Conquer: Solve sub-problems Combine: Combine the sub-problems solutions by convexity constraints. Does this make sense?
