SUMMARY:C&O Reading Group - Rian Neogi
CLASS:PUBLIC
DESCRIPTION:TITLE: Bipartite Perfect Matching is in Quasi-NC\, Part II\n\n
 SPEAKER:\n Rian Neogi\n\nAFFILIATION:\n University of Waterloo\n\nLOCATION
 :\n MC 6029\n\nABSTRACT: Mulmuley\, Vazirani\, and Vazirani gave a random
 ized parallel\nalgorithm for checking whether a perfect matching exists in
  a graph.\nIn doing so\, they came up with the infamous isolation lemma\, 
 which\nfound several uses in other areas of computer science. The isolatio
 n\nlemma is inherently randomized\, and it has been a long-standing open\n
 problem to derandomize the lemma. In this talk\, I will go over the\nbreak
 through work of Fenner\, Gurjar\, and Thierauf where they almost\ncomplete
 ly derandomize the isolation lemma in the special case when\napplied to th
 e bipartite perfect matching problem. In doing so\, they\ngive a determini
 stic parallel algorithm for perfect matching that uses\na quasi-polynomial
  number of processors.
