I'm a huge fan of Tetris and have played them all. I think this version is the best one. Not only because of the drama behind it, but two player mode is actually pretty fun.
Recently got Tetris Grand Master 4 and played it with an arcade stick insanely satisfying to play that way and with that ruleset and kinda ruined other versions/input methods for me.
I was expecting something like DQN, but what I actually saw was a new approach, so it was fascinating. Usually when you're making small AI demos and doing hands-on exercises, you work with Tetris a lot.
In NES Tetris, if the input is the same, the result is the same, so you can store all the inputs and reproduce specific moments. The state becomes like a graph, which allows for fuzzing testing. It's interesting
Seems to be influenced by the pieces on the board. Bill talks about it a little in the article. You do seem to get more | shaped pieces when you leave those spaces open on the board.

I don't think this is correct, nor that it can be evinced from the article. What it does say is that the sequences that led them to achieve their target show a higher incidence of I shapes. This is because all the ones that show less I shapes have been "pruned away" by the cost function, which favors I shapes.
This has some relationship with the anthropic principle: isn't it strange that, of all the possible universes, we ended up in the one that seems fine-tuned exactly for life as we know it?
Their strategy optimized for the I pieces, so it should be no surprise that winning runs were ones that had a higher incidence of those pieces. Runs with fewer would not have survived under that strategy.
The best versions of Tetris are random in sets of 7. There's a "bag" of all 7 shapes and the next piece is picked from that bag until the bag is empty and then it refills.
You're talking about piece, right? I know that it's actually determined by the execution state per frame and the button inputs [1]. I looked into Tetris AI before because I found it fascinating, but I might be mistaken.

how doe piece selection work? isnt it random?
