The Hardest Part of the Solution to the Rubik's Cube
In simulation, you can have infinite amount of data. And single AI that can solve all of them ends up working well with the reality. We just pick parameters randomly and an in simulation model just goes for thousands of years and keeps on solving Rubik's cube in each of them. The thing is the neural network that we used, it has a memory. As it presses for instance, the side of the of the cube, it can sense. Oh, that's actually this side was difficult to press, I should press it stronger. This kind of a memory that model came through that process of interacting with the cube in the simulation.
