Hello everyone,

I am used to work with MIP, but recently tried some modelling with the CP-Optimizer. I was recently asked which consistency level (domain consistent, bound consistent) was applied to the constraints of my model.

How can I find out about this? Is this something I define or is it defined by the solving algorithm/constraint type?

Thanks in advance for any help

Hi David,

There isn't a generic answer to your question.
The consistency level depends on the type of the constraint and the most often can be be leveled up or down using Inference levels.
You would find more information here.
