Course Description

A variety of combinatorial existence theorems will be proved by algorithms which tell how to find an instance of what is asserted to exist.
Another main purpose will be to introduce polyhedral combinatorics, which uses systems of linear equations to obtain algorithms and theorems.
Emphasis will be on matroids and polymatroids with a variety of applications, especially to tree systems and branching systems in networks.
Books and graph theory and combinatorial optimization will be resources.
Drafts of notes will be incrementally available.


Some quotes from the book 'Combinatorial Optimization', by Lex Schrijver (Springer, 2000)

"Pionereed by the work of Jack Edmonds, polyhedral combinatorics has proved to be a most powerful, coherent and unifying tool throughout
combinatorial optimization. Not only has it led to efficient (that is, polynomial-time) algorithms, but also, conversely, efficient algorithms often
imply polyhedral characterizations and related min-max relations. It makes the two sides closely intertwined."

" In the 1960's Edmonds advocated calling an algorithm efficient [or "good"] if its running time is bounded by a polynomial in the size of its
representation. Since then, this criterion has won broad acceptance, also because Edmonds found polynomial-time algorithms for several
important optimization problems"

"Edmonds conjectured that there is no polynomial-time algorithm for the traveling salesman problem. In language that was
developed later, this is equivalent to
NP≠P."
