Soon we should have Pathfinder implemented and this will get rid of lots of these minor modes automatically.

Who can tell me about Pathfinder (or point me somewhere)? There’s nothing in the forum.

Maybe @Bob_Carpenter? I found this:

  • Pathfinder : parallel algorithm to find first reasonable draw; with Lu Zhang, Ben Bales, Aki Vehtari, Andrew Gelman

Actually, maybe @Lu.Zhang?

Pathfinder is a new fast and stable approximate algorithm that can also supply starting points for HMC. The project is led by Lu, Bob, and Aki, and we should have a draft paper soon to share with the world.
