Find, read and cite all the research you need on ResearchGate Dantzig–Wolfe decomposition is an algorithm for solving linear programming problems with special structure. It was originally developed by George Dantzig and Philip Wolfe and initially published in 1960. Many texts on linear programming have sections dedicated to discussing this decomposition algorithm. … See more In order to use Dantzig–Wolfe decomposition, the constraint matrix of the linear program must have a specific form. A set of constraints must be identified as "connecting", "coupling", or "complicating" constraints wherein … See more There are examples of the implementation of Dantzig–Wolfe decomposition available in the closed source AMPL and GAMS mathematical modeling software. There are general, … See more After identifying the required form, the original problem is reformulated into a master program and n subprograms.
