fnl4461

The instances u724, rl1304, pr2392 and fnl4461 are introduced by Stefanello et al. (Stefanello F, Araujo O, Müller FM (2015) Matheuristics for the capacitated p- median problem. International Transactions in Operational Research 22 (1):149-167) and adapted from the TSPLIB. They use the original coordinates of the demand nodes and compute the demands on the basis of integer uniform random variables in the interval [1; 100]. The number of sources are determined on five different sources/destination ratios. The total supplies are approximately 125% auf the total demands.
