Dear all,

I'm solving multiple problem instances for the VRP, each instance is in a separate file. I created a loop that reads each file, solves it and improves it using guided local search, stores the results, and moves on to the next file.

After solving several files (say 5 files), I get this error message on the sixth file:

Error: IloIIM: IloScanNHood: detected anamalous neighborhood behavior -
IloNHoodI::define should return the same delta for the
same given index.

The sixth file is read smoothly, but when the code reaches the guided local search part, it gives this error message. Any idea why? Or I can fix this?

Hello,

Which version of solver/IIM/Dispatcher do you use?
If you use the most recent ones, you should send your data set to the customer support.

Cheers,

Amelie.

Hi,

Yes, I confirm CP 1.5 - Dispatcher 4.7 is the most recent version.
Do you have access to the customer support? If yes, could you please send them your data set + code so that we could further investigate ?
Cheers,

Amelie.
