Logiles at http://plato.asu.edu/ftp/mpec_logs/

Medium-sized examples from the following sources were solved:
http://www-unix.mcs.anl.gov/~leyffer/macmpec/
http://www.gamsworld.org/mpec/mpeclib.htm

The following codes were run in default mode on a 2.4 GHz Opteron 4GB RDRAM, Linux-2.6). For accuracy reached, see logfiles. Other codes/problems will be added when available.
