The single row facility layout problem is the problem of arranging facilities with given lengths
on a line, while minimizing the weighted sum of the distances between all pairs of facilities. The
problem is NP-hard. In this paper we present path relinking algorithms to solve large sized
instances of the problem. We use three different metaheuristics to generate sets of good quality
initial solutions and subject the solutions in these sets to path relinking. We present our
computational experience on 43 benchmark instances with up to 110 facilities.
