Multi-objectivising the Quadratic Assignment Problem by Means of an Elementary Landscape Decomposition Authors: Jose A. Lozano,Alexander Mendiburu,Josu Ceberio,Borja Calvo In the last decade, many works in combinatorial optimisation have shown that, due to the advances in multi-objective optimisation, the algorithms in this field could be used for solving single-objective problems. In this sense, a number of papers have proposed multi-objectivising single-objective… Springer International Publishing	2015-01-01
