Buss Mathematics Department, Princeton "The Polynomial Time Hierarchy and Fragments of Bounded Arithmetic" UNIVERSITY OF TORONTO DEPARTMENT OF COMPUTER SCIENCE (SF = Sandford Fleming Building, 10 King's College Road) (MC = McLennan Physical Laboratories, 60 St. George Street) (RS = Rosebrugh Building, Taddlecreek Road) THEORETICAL ASPECTS SEMINAR - Friday, February 22, 10 a.m., MC 252 Dr. Amos Israeli Computer Science Department Technion, Haifa "A Fast and Simple Randomized Parallel Algorithm for Maximal Matching" * A parallel randomized algorithm to find a maximal matching is presented. Its expected running time on a CRCW-PRAM with |_E| processors is 0(_l_o_g|_E|). The expected time is independent of the structure of the input graph. This improves the best known deterministic algorithm by a factor of log829|_E|.
