[Help-glpk] Entering Feasible Solutions and setting optimality tolerance for MIPs

Wed, 09 Mar 2005 09:52:56 -0800 

I'm just in the process of exploring how to use GLPK for MIPs and was wondering if there is a simple way to do either of the following:
 
1.    Setting the optimality threshold for early termination.  (E.g., terminate when best recorded feasible is within 5% of optimal)
2.    Specify a feasible integer solution for use in fathoming branches.
 
Also, does GLPK implement any sort of cutting plane methodology?
 
thanks,
 
DS
