TSPLIB entries are averages for the following instances:

N=1000 pr1002, pcb1173, rl1304, nrw1379
N=3162 pr2392, pcb3038, fnl4461
N=10k pla7397, brd14051
N=31k pla33810
N=100k pla85900

Note: This may not be a typical sample, since we had to pick instances that most codes
could handle, thus ruling out the many TSPLIB instances with fractional coordinates.
