I have not quite understood yet what they do exactly.

Ok the use a NN to provide an estimated solution time. The NN is trained to match the estimated solution time to the one estimated from a 1-ply search. In chess this an old idea (match the heuristic evaluation function to the result of a 1-ply search).

Can it beat this guy though who solves 17x17x17 cube in about 2 hours ? https://www.youtube.com/watch?v=7ChuKKL2PpU

I would like to understand what makes it a unique challenge. From what I understood from the abstract

- single goal state
- solved in reverse with root node being that single goal state (i.e. solved state)
- finds shortest path 60% of the time

Please add more if you read the full paper.

In a world first, researchers at the University of California have developed a computer algorithm that can solve a Rubik's Cube without a neural network, machine learning techniques, "specific domain knowledge," or human assistance.

And this

By successfully being able to solve a Rubik's Cube without initially being trained on previous information, the DeepCubeA algorithm represents the gradual shift in machines from making carefully-directed computations to making those which appear to resemble human-like reasoning and decision-making.

I've seen this video, probably some ad hoc solution, but funny:

The basic idea as I understand it is to solve inner faces first, then edges and the rest is solved just like a classic 3x3 cube.

(I admit that I never managed to solve a rubik's cube myself

Long ago when the cube first came out I bought one and managed to find an algorithm to solve it. Unfortunately I lost a girl friend in the process...
