Query: Statistical mechanics of optimization problems   Here I will present an introduction to the results that have been recently
obtained in constraint optimization of random problems using statistical
mechanics techniques. After presenting the general results, in order to
simplify the presentation I will describe in details the problems related to
the coloring of a random graph.
