In many organizations people need to locate colleagues with knowledge and information to resolve a problem. Computer-based systems that assist users with finding such expertise are increasingly important to industrial organizations.

Despite the existence of e cient solution methods for bin packing problems, in practice these seldom occur in such a pure form but feature instead various considerations such as pairwise con icts or pro ts between items, or aiming for balanced loads amongst the bins. The Wedding Seating Problem is a combinatorial optimization problem incorporating elements of bin packing with con icts, bin pack...
