Hello,

There are a variety of filtering techniques for propagating the cumulative constraint, such as edge-finding, not-first not-last, time tabling, etc. I wonder if they are all implemented in the ibm scheduler? If so, in what order and priority? Are these algorithms used individually or in conjunction with each other?

Thanks

Hi,

Yes, most of the filtering techniques for cumulative constraints like the ones you mention are implemented in CP Optimizer.

However I'm sorry we cannot reveal much about how these constraints work together in detail.
