• Rearranging the characters on a T9-style keyboard can reduce the number keystrokes per character typed (i.e. increase the typing efficiency of the keyboard)
• The improvement is enough for a 6-key layout to achieve similar efficiency to the standard T9 keyboard (8 keys)

The write-up for this project can be found here: https://torvaney.github.io/projects/t9-optimised

• Run the optimiser with python src/main.py.
• View results in data/results.json and optimised keyboards in images/...

Train and test data has been included in data/. To run the optimiser on different text, simply change these files.
