IE418 Lecture 9 2 Combinatorial Algorithms for Integer Programming Some integer programs can be solved using so-called combinatorial algorithms , which do not rely on polyhedral theory. For example, there are various combinatorial algorithms for solving minimum cost network flow problem and special cases. Shortest Path Problem Maximum Flow Problem Matching Problem Another related example is the Minimum Cut Problem . Algorithms for these problems are covered in more detail in a network flows course.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
