"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|.
