Re: [Help-glpk] GLPK re-endrant

[Robbie Morrison]

Hi Antonello

Can you post your conclusions back to this list?  I do
something similar: my "agents" are plant operators, market
participants, are engineering equipment.  At present I just
make and reset little GLPK instances.  No performance issues
at present, but this strategy could well scale rather badly.
