I'm having issues getting comparison operators to behave in optimizer constraints.
For example, the following :
...doesn't reject solutions where the values are equal :
One of our clients wanted a working equivalent to a != b, which I think should be "a<b or a>b" in an optimizer constraint. In the end the best working solution I could give him was abs( - ) >= 1.
OptQuest constraints can only support greater-than-or-equal, less-than-or-equal, or exactly equal. If you use less-than or greater-than, it treats it as less-than-or-equal or greater-than-or-equal. http://www.opttek.com/documentation/v64engine/OptQuest%20Engine%20Documentation/WebHelp/Defining_con...
I will add a note to the development list to update the OptQuest documentation accordingly.
You can adjust your constraint equation by a small value in order to get the results you are looking for:
[Variable 1] <= [Variable 2] - 0.01
