WebDantzig-Wolfe decomposition is often powerful if you can exploit the structure of the individual blocks in your pricing problem. Again, this often means to apply a shortest path or some other combinatorial algorithm. But as I said, it is very dependent on the structure of the problem. There is no all-fits-one solution, it is highly problem ...
