Hi all,

Does anyone know something about the obsolete function IlcActive(IlcGoal) ?

I'd like to know if the code of
IlcActive(IlcGoal1)
IlcActive(IlcGoal2)

is equivalent to do :
solver.solve (IloAndGoal (_Env, IloGoal1, IloGoal2)) ?

I can't find any old documentation about it...

Thanks a lot!
Best regards!

Hi Alex,

Yes at the toplevel you can consider that:

IlcActive(IlcGoal1)
IlcActive(IlcGoal2)

is equivalent to do :
solver.solve (IloAndGoal (_Env, IloGoal1, IloGoal2))

In Solver 4.x there was a notion of edit mode.
If the manager is in edit mode, what I said "at the toplevel", you can consider this works as you have understood.
If the manager is not in edit mode (that is, it is in search mode), the behavior is a little bit different (let us know if you really need more details about this).

Regards,

Chris.

Hi,

Thanks for your answer. Actually it is in no Edit mode....

Hi Chris,

For the current development i made, i've used IloAndGoal in the solver.solve() to replace the calls of IlcActive used in the older version which worked with a manager (IlcNoEdit). But the solver doesn't find a solution....

I would appreciate if you could explain me how to reach the same behavior than C

Hello,
In general, solver.solve(IloGoal g, ...) can be used only at the top level of the search so if no exception is thrown in your code, even if the solver is in NoEdit mode, I guess it means that you are at the top level of the search and, in this context, the IloAndGoal should result in the same behavior as the two active goals. By the way, if you want to use some internal solve during the search, you need to use solver.solve(IlcGoal g,...) instead (with an +IlcGoal+).
To understand the difference of behavior, I think you should analyze more in detail how the two searches run and which decisions are taken and in which order by adding some printing information in your goals.

Hi !
Thanks for your answer.
Actually, i have an exception if i do
LfinalGoal = IloGoalTrue(Env) && LGoal1...

instead of
LfinalGoal= IloInstantiate (_Cost) && LGoal1 ...
