A code that was working under ILOG CPLEX 12.2 is not working under a new version 12.9.

The error is "setVectors is not a member of IloCplex"

The following site also states that setVecotrs is removed since 12.70. However, all recent manuals (including that for 12.10) mention setVectors can be used to provide starting solution.

This is not an answer.

I am providing the link of the site that states setVecots is removed:

https://perso.ensta-paris.fr/~diam/ro/online/cplex/cplex1271/CPLEX/ReleaseNotes/topics/releasenotes127/removed.html

I got the answer:

Lists changes in the C++ API and advises conversion steps.

These methods of the C++ API of CPLEX V12.5 have been deprecated and will be removed in a future

release:

• IloCplex::setVectors
• IloCplex::SolveCallbackI::setVectors

Use these new or existing methods instead of those deprecated methods to add one or more starting

solution candidates:

• IloCplex::setStart
• IloCplex::addMIPStart
• IloCplex::SolveCallbackI::setStart

Hi,

Looks like IloCplex::SetStart is the correct replacement for SetVectors method (you can compare that both have the same parameters - types and names).

SetVectors:

SetStart:
