(In my code I leave those at default values. There are also two other Benders-related parameters, in Java .feasibilitycut and .optimalitycut, that set tolerances for feasibility and optimality cuts. If either all the variables are integer (no LP subproblem) or none of them are (no MIP master problem), CPLEX throws an exception.

Note that this will not stop manually coded Benders from working (as in my MANUAL method) it just stops CPLEX for creating a decomposition. -1 = OFF: Use standard branch and cut, doing no Benders decomposition (even if annotations are present).It is integer valued, but for some reason is not part of the IloCplex.IntParam class hierarchy (which threw me off at first when I tried to use it in my code). The key to all this is a new parameter, whose Java name is.

Let CPLEX decide how to split it into a master problem and one or more

The code for the revised example is in this Git repository, and is free for use under a Creative Commons 3.0 license. To get a feel for the new features related to Benders, I rewrote that example. I've previously posted Java code for a simple example of Benders decomposition (a fixed-cost warehousing/distribution problem). For details on that (and other changes to CPLEX), I suggest you look at this post on J-F Puget's blog and Xavier Nodet's related slide show. After doing this, you should not get CPXERR_RESTRICTED_VERSION any more.As of version 12.7, CPLEX now has built-in support for Benders decomposition. In the example above, you can see that COSDIR was /home/rkersh/opt/CPLEX_Studio128 and platform was x86-64_linux. Stored in directory: /home/rkersh/.cache/pip/wheels/88/19/c6/6545d3d5ac65b18b796b44986272e17f3a8429df7b12472624įound existing installation: cplex 12.8.0.1įor the first command, COSDIR is the location you installed CPLEX Optimization Studio and platform is something like x86-64_linux, 圆4_win64, x86-64_osx, etc. Processing /home/rkersh/opt/CPLEX_Studio128/cplex/python/2.7/x86-64_linuxīuilding wheels for collected packages: cplex For example, you can do something like the following: $ cd /cplex/python/2.7// This would work for you system Python or for a virtualenv.

Another alternative is to install the academic version of the cplex package over the top of the free "community edition". As suggested in the other answer, you can use the PYTHONPATH environment variable.
