1° To get the students acquainted with graphs, which are an essential tool in combinatorial optimization, with many applications to various problems in networks, and which will appear in other courses.
2° The focus will be on modelizing problems and on the existence of general results and techniques.

Graph search, components, trees, paths, flows and connectivity, min-cut (routing, fault-resistance), arc-disjoint paths (traffic assignment); Compatibility and conflicts: matching (client-resource assignment), coloring (frequency assignment), domination (location of concentrators); Miscellaneous: Eulerian cycles, Hamiltonian cycles (vehicle routing), broadcasting and gossiping, etc. Principles of operations research. Some other fundamental ideas of graph theory, some results and methods of combinatorial optimization like spanning tree, optimal path, scheduling, heuristic algorithms are exhibit by formulation and computation exercises.

None but requires a good mathematical skill.
