Solving terminal assignment problems with groups encoding: The wedding banquet problem
This paper presents an extension of the terminal assignment problem (TA) in the case that groups of terminals must be assigned together. We analyze this situation by means of an e...

Exploiting group symmetry in semidefinite programming relaxations of the quadratic assignment problem
We consider semidefinite programming relaxations of the quadratic assignment problem, and show how to exploit group symmetry in the problem data. Thus we are able to compute the b...

A (1-1/e)-approximation algorithm for the generalized assignment problem
We give a (1 - 1/e)-approximation algorithm for the Max-Profit Generalized Assignment Problem (Max-GAP) with fixed profits when the profit (but not necessarily the size) of every ...
