About Bob Hanson's solver

1. I am sure that Bob Hanson's solver does NOT do locked candidates type 2. It finds the eliminations by X-wings, strong chains or even "hypothesis and disproof", even though it claims to do so... is there any reason for this?

2. What exactly is "3D Medusa chain analysis"? I have read the explanations and don't really understand.

I don't know anything about Bob's solver, but to find out about specific techniques try either Sudopeida or The Collection of Solving Techniques. 3D-Medusa is colouring with both bilocals and bivalues. Here a a couple of posts from the Collection:

That solver has been there for a while, I'm not sure if there was any recent updtae to it.

Most of these web solvers are based on information back in 2005. (I think also the one by rubylips)
