Two notable branches of discrete optimization are:
- combinatorial optimization, which refers to problems on graphs, matroids and other discrete structures
- integer programming
These branches are closely intertwined however since many combinatorial optimization problems can be modeled as integer programs (e.g. shortest path) and conversely, integer programs can often be given a combinatorial interpretation.
