My point exactly. As a vendor I can say I have no trouble making sure our software works with CBC, but last time I gave it a look, I realized the code is specialized to Clp. The generic version ran so much slower, that I lost interest. I think a fast version of Cbc that uses Osi (which might need a rewrite) would be nice and in the spirit of the original idea of solver independence. <br>

Just a suggestion.... <br><br>If COIN intends to actually support other solvers (besides CLP/CBC), they should probably have one machine with access to all supported solvers and some kind of script to compile and run a unit test against all solvers - so that developers can check this before a commit.<br>
<br>I'd much rather see FULL support for 1,2 or 3 solvers than partial support for a bunch where most things don't work. I would think that each vendor would "donate" a few hours a month to making sure COIN/OSI/etc worked correctly with their solvers. If not, COIN should probably just drop support of that vendor. Doesn't make much sense to have partial support.<div>
