CS202/2005/OldAnnouncements

Note: You are looking at a static copy of the former PineWiki site, used for class notes by James Aspnes from 2003 to 2012. Many mathematical formulas are broken, and there are likely to be other bugs as well. These will most likely not be fixed. You may be able to find more up-to-date versions of some of these notes at http://www.cs.yale.edu/homes/aspnes/#classes.

2005-10-21: The proof of Hall's Theorem in class today evaporated when I forgot how to extract an augmenting path from the sequence of nodes found by applying Hall's condition starting from an unmatched node. See BipartiteGraphs for a working proof or CS202/Schedule/2005-10-21 for an explanation of the missing piece.
2005-10-20: CS202/Assignments/HW06 has been clarified: the partial order in problem 2 is now explicitly a strict partial order (see Relations for the distinction between an ordinary partial order and a strict partial order).
