โฆ Synopsis
An extremely simple distributed randomized algorithm is presented which with
ลฝ
. high probability properly edge colors a given graph using 1 q โฌ colors, where โฌ is the maximum degree of the graph and is any given positive constant. The algorithm is very ลฝ fast. In particular, for graphs with sufficiently large vertex degrees larger than polylog n, . ลฝ . but smaller than any positive power of n , the algorithm requires only O log log n communication rounds. The algorithm is inherently distributed, but can be implemented on ลฝ . ลฝ . the PRAM, where it requires O mโฌ processors and O log โฌ log log n time, or in a ลฝ . sequential setting, where it requires O mโฌ time.

In the leader election problem, n players wish to elect a random leader. The difficulty is that some coalition of players may conspire to elect one of its own members. We adopt the perfect information model: all communication is by broadcast, and the bad players have unlimited computational power. P
