aries or fape for non-hierarchical planning? #36

Closed d-vyd closed 2 years ago

d-vyd commented 2 years ago

Hi folks. I'm trying to compare temporal planners (tdf, optic, etc). Should I include aries or fape for non-hierarchical planning? It looks like aries is the current project, correct? I started with fape after reading some of Arthur's publications. Right now I'm unable to make performance comparisons because I seem to be calling fape incorrectly. No matter what I do, I get an exception on Windows 11 64bit machine. EDIT: I think the problem is my java environment. I'll change that.

Aries currently supports non-temporal planning in the sense that it can translate a flat problem into its own representation and use its internal constraint solver to look for a solution. However, there has been no effort in making the solving efficient for flat-problems (notably with branching heuristics and symmetry breaking) and as a result you will not get state-of-the-art performance for such problems. The current focus is on hierarchical planning for which much better results can be expected. We do have plan to improve the story for flat planning but I cannot give a timeline at the moment.

Got it. Thank you for writing!
