This slides give a minimal introduction: http://www.coin-or.org/Presentations/CORSINFORMSWorkshop04/coin-osi.pdf Concerning the OR math, mixed integer programming can be done with some tricks by traditional LP methods (Branch and Price?), but I think the CBC code uses more advanced methods. If CLP handles basic MIP we could do with that for now. I understand the OSI interface lets you choose several solvers, some free, some commercial. -- Configure bugmail: https://issues.apache.org/ooo/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
