It does sound like an optimizer app but hard to say.
In terms of ML, I've been able to do a lot of regression algorithms but not any that require iteration, like most classification algorithms (clustering, segmentation). Those I usually do outside of Anaplan.
So, I guess this piqued my interest. Is this an app that can be seen in the app hub? Since this was a link shared with the partners I'm assuming it's something we can take a look at. Same as @abhay.kanik I'm not sure where to look.
Unfortunately, I don't have access to the optimizer. I think you have to be part of an enterprise license.
@JaredDolich it is possible to do iterations using the time dimension but you have to think of it not as time but as the dimension which iterates. I have only done this once before in an extreme case and would not advise it! But it was interesting to experiment!
