This method is applied to a lattice simulation of a homopolymer chain undergoing a coil\-to\-globule transition upon cooling. We select the optimal number of replicas for different chain lengths, N = 25, 50 and 75, using replica's round\-trip time in temperature space, in order to determine energy, specific heat, and squared end\-to\-end distance of the homopolymer chain for the selected temperatures. We also evaluate relative merits of this optimization method."]
