Graph algorithms Study guides, Class notes & Summaries

This summary contains all material taught in the course Combinatorial Optimization to 3rd years Business Analytics student at the VU Amsterdam. I found the information in this course quite overwhelming and hard to understand without the right examples. Therefore, I combined the material from the slides and the book with extra explanations found on internet or lectures from similar courses. The summary contains a lot of examples, for both the theoretical (simple graphs are drawn to visualise th...
