Add maximal delay constraint for startBeforeStart, startBeforeEnd, ... constraints

I often have a constraint between interval variables that limit the maximum delay between the start/end and start/end of interval variables. I'd like a native, efficient method for implementing this constraint. I currently use constraints using fu...

Empty links in CPLEX Optimization Studio Documentation

There are many 'empty' links/pages in the CPLEX Optimization Studio Documentation when I search for topics. I limit the scope to CPLEX and IDE, but still get many, many blank results. I spend a great deal of time clicking through blank pages to fi...

Bring MATLAB interface back for CPLEX

Please bring back the MATLAB interface for CPLEX. We rely heavily on this feature since toolboxes we use are Matlab exclusive.
