NN for solving the Rubik's Cube would be like killing a mosquito with an artillery bomb: not necessary at all.

Although not related to the OpenAI paper. Solving Rubik's Cube via Deep Learning shows that you can teach a system to learn how to solve the problem. That's a very different problem that programming the God algorithm.

Isn't that a trivial observation about sequences? More interesting is whether i) it is cost efficient, ii) the solution is generalisable, iii) whether we learn anything from the solution. You can dig a hole with sieve but is it the best tool?

Training a system to implement an algorithm on its own is a different problem than formulating a solution by hand. Now if a DL can discover the God solution, then that's a massive breakthrough.

Go a step back: when you already know the solution and the exact steps to get there (plus how to do it in a much simpler and straightforward way), you don't need

You don't know how a cube is scrambled. That's not a given.

Solving Rubik cube through RL is already done before and so I believe
@openai goal wasn’t that. The focus was real-world manipulation task and sim2real.https://www.nature.com/articles/s42256-019-0070-z …2 replies 1 retweet 6 likes -

ps deep rl + search ≠ deep rl. that paper to is a hybrid.

Hopefully MCTS band-aid will go away some day. However I felt blog+paper were very clear on using Kociemba’s algorithm. Also pleasant trend of describing open issues, i.e., (1) 80% attempts fail on hard config (2) custom cube communicates state (3) 13K years cummulative training.

Very clear in a single sentence ref 111 (!), not in opening sentences or tweet (or video?). Most readers would not have realized, given the framing.

Solving Rubik’s cube is indeed magical for non-technical audience but this has been done regularly including robotic hands. RL based approaches are also nothing new. For me, this wasn’t the most interesting part. I was more bummed by the fact it wasn’t fully vision based.
