The conference was organized by László Lovász (Redmond) and Hans Jürgen Prömel (Berlin). The programme consisted of 15 lectures, supplemented by 21 shorter contributions, and covered many areas in Combinatorics such as partition theory, discrete geometry, homomorphisms and lattices, extremal combinatorics, graph theory, random structures, and additive number theory. The aim of the workshop was to emphasize the underlying methods that are common to many of these combinatorial branches and that act as both driving forces and organizing principles of the field. The diversity of the topics and par\-ticipants stimulated a lot of fruitful discussion between the different branches and gave rise to new collaborations, in particular for the younger generation of researchers.
