Warm Start and setWarmStart

[emunsing]

Hi there! I've used warm-start for a number of problems in the past, and have immensely appreciated the speedup which it gives when using CyLP! However, I'm now working on a problem which is in a project where persisting the CyClpSimplex model between solutions would be architecturally difficult, and so I'm wondering whether it is possible to transfer information from one model to another to facilitate warm-start.

Is it possible to feed in an initial state to warm-start the solver? I don't see any way of setting the variable initial values. However, I see that COIN-OR has a setWarmStart implemented for CLP which allows us to initialize from a snapshot. It doesn't appear that this is exposed in CyLP; is there some solver option to utilize this?

Is there a packet of information which CyLP persists which allows for warm-starting, and can this information be extracted from one model and set in another model?

Thanks for all your great work; this is a really valuable tool for research! 🙏 👏
