While the Hchl Problems are tested on DEC Alpha (processor 21164, 500 Mhz and 1 Gbytes of RAM) the others are tested on a UltraSparc1 (145 Mhz, 64 Mbytes of RAM, under Solaris 2.5 with CPU time limited to 2 hours and virtual memory limited to 300 Mbytes). All approaches were coded in C .The presented results generated with the NVMB-BOB* algorithm.
