This course provides an introduction to foundational theory and algorithms of discrete mathematics. Instead of covering a variety of approaches and algorithms, the course focusses on those methods that have proved to be superior to alternative techniques and have become "workhorses" in modern applied mathematics. For instance, the theory of the Simplex Algorithm is worked out carefully, while other less practical or less efficient algorithms for linear programming are not covered. Aside from the algorithmic aspect, the course has a substantial theoretical component: graph theory, proofs of correctness of algorithms, and the structure of polyhedra.
