I'm using the getValue() function to check if my cuts are violated at the current relaxation or not.
It seems that this call is very expensive in terms of CPU time (much more than addLocal() or any other operation I do).
Does anyone know why it is so expensive ?
Is it better to call getValue() on an IloExpr ?
Any comments on that ?

I'm using Ilog Cplex 10.1.

Are you retrieving each variable value individually?  There is a certain amount of overhead in this, so you may get better performance if you retrieve several values at a time by using the array version, getValues().
