What problem can arise when the number of commodities is only one when looking at a multi-commodity flow problem?
This question was asked by my professor in the context of column generation and branch-and-price.

When you have a multi-commodity flow problem with only one commodity then the problem reduces to an ordinary network flow problem. It is still possible to apply column generation and branch-and-price algorithms, howevere, ordinary network flow problems will be much faster in most cases.
