From the reviews: "This volume is a collection of survey papers in combinatorics that have grown out of lectures given in the Workshop on Probabilistic Combinatorics at the Paul Erdos Summer Research Center in Mathematics in Budapest . The papers ... will be appreciated by specialists and general mathematicians alike: ... each paper gives a quick introduction to an active area, enabling the reader to learn about the fundamental results and appreciate some of the latest developments. An important feature ... is the abundance of open problems." (L'Enseignement Mathematique, Vol. 48 (3-4), 2002)
