    I have from my older Cplex 10 documentation that variable priorities are integers starting at 2147483647 and working downward. That is, higher number priorities are processed first, and the highest value allowed is 2147483647. I can not find a similar guide in my OPL 6 documentation. Is this still accurate? I do not have the Cplex documentation for Cplex 11 (it is not provided with OPL licenses).

    Hi,

    Priorities set using
    cplex.setPriority
    are passed as is to CPLEX and handled as described in CPLEX documentation.

    The methods in script on the cplex object are just wrappers of the methods in C++ CPLEX in Concert. This is the right place to get detailled documentation.

    Here at the university, we have retrieved all of the PDF documentation from ILOG's license support website, and have had it professionally printed and bound. We have found that the software help feature has additional documentation not present in the pdf files.

    A search of the help application with variants of the word "priority" reveals instructions to implement priorities, but does not reveal the documentation I am looking for. The set of supplied pdf files does not include a manual devoted to c++ concert or cplex.
