Pinned topic combined objective and dexpr's

Hi,

Reading ODM manual, it seems to me that dexpr's should be combined in the objective function only with 1 or 0 weights. Is that true?
I've been trying to use dexpr's with more complicate - but still linear - relations among goals, and they are not correctly shown.
Sometimes the solver behaviour is not the same as in OPL IDE.

TIA,

    Got it now - no parenthesis and no variables to keep weights value.

    hello there,
    basically you mean everything works, but the doc was not so good to find out what you needed?

    cheers

    I thought that there were explanations only in the section I read.
    But somewhere else in the manual I've found the reason for my mistakes.
    Unifying is not easy, but maybe some redundancy would help.

    I appreciate your interest in my complaint.
