2048-rs
This is a Rust implementation of the famous 2048 game which runs in the terminal.
In addition to the standard user inputs, an AI can be used to perform the moves. This AI leverages the expectiminimax algorithm to recommend the best next move at each step.
Statistics
Here are the statistics of the AI with its default parameters:
max tile reached | frequency |
---|---|
2048 | 100 % |
4096 | 100 % |
8192 | 96 % |
16384 | 70 % |
32768 | 10 % |
In particular, these statistics correspond to a minimum branch probability of 0.001
.
Decreasing this value would lead to better performance, as more branches would be explored, but this would also take more time.
Some other hardcoded parameters can be tweaked in order to further improve the algorithm. I have not performed an exhaustive grid search, thus the parameter set is probably sub-optimal.
Installation with Cargo
Then, in order to play:
Installation from source
> git
> cd
> cargo
Usage
You can change the probability of drawing a 4 tile:
> play-2048
Or adjust the minimum branch probability of the expectiminimax search:
> play-2048
To get the list of available options, simply run:
> play-2048
