This is actually described in the lp_solve documentation under the description of the LP file format, where it states:
<constraint> is an optional constraint name followed by a colon plus a linear combination of variables and constants or (just one) constraint name followed by a colon (a range) or (just one) variable name without a colon (a bound), followed by a relational operator, followed again by a linear combination of variables and constants, ending with a semicolon. The relational operator can be any of the following: "<" "<=" "=" ">" ">=". There is no semantic difference between "<" and "<=" nor between ">" and ">=" (even for integer variables!). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1334411 Title: integer constraints in lp format do not seem to be respected To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lp-solve/+bug/1334411/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
