Team There #39;s a couple of features documented in 4.34 in the stand-alone solver section (Appendix D):
(Options specifi c to simplex method) --bas fi lename read initial basis from filename in MPS format --wbas fi lename write nal basis to fi lename in MPS format Both are missing from the glpsol that I built on cygwin/Windows Vista, for versions 4.34 as well as 4.39. Now, documentation for 4.39 does NOT mention these features - so that #39;s at least consistent. I suspect this feature existed earlier on. I think this could be a useful feature to keep, and I can quote my case here. I am essentially solving a large-ish LP whose parameters are generated by incrementing one parameter value. And so, I dont expect too many changes in the solution for a large part of my increments, and hence using a final basis for one solution as an initial basis for the next could save a lot in time.
