Duality and column generation
4 important questions on Duality and column generation
What does the primal and the dual generate?
What is considered weak duality?
What are the consequences of weak duality?
- When w=z the feasible basic solutions are optimal for the primal and the dual problem;
- If the primal is unbounded, the dual has no feasible solutions;
- If the dual is unbounded, the primal has no feasible solution;
