Hello:
Running a rather large model and I get the following output (see below), which
is solved by AMPL in about 17 minutes (very old 32 bit version).
All other testing runs quickly (smaller models) for this glpk 32 bit version
(4.47).
When I try the 64 bit version, I error at line 70 of glpenv05.c almost
immediately.
Any thoughts on how to proceed?
Thanks!
