HTML5 Turing Machine Simulator

Live version: https://unstable.life/turing-machine-simulator/

Functions

• Simulation of single-tape and multi-tape TM
• Simulation of deterministic and non-deterministic TM
• Save/load: by link, to file, to localStorage
• Interactive graphical editor
• Interactive graphical simulator
• Helpful error messages!

Basic usage

Clone and open the index.html in your browser. Should work nicely in Chrome and FF.

• Write input to tape(s)
• Fill in the table
• Table input format: (NEXT_STATE, WRITTEN_SYMBOL, TAPE DIRECTION)
• Example: (qacc, > , R) will go into state qacc (accepting state), current field will be overwritten with '>', and the head will move to the right
• Non-determinism example: Just write more tuples like (qacc, > , R), (qrej, > , R) the TM will choose one randomly (or you can choose manually during the simulation)
• Multi-tape example: Increase the tape count and the table reformats, the input format is as follows: (NEXT_STATE, S1, S2, S3 , D1, D2, D3), where S1-S3 are symbols written to tape 1 to 3 and D1-D3 are head movement directions.
• Check the included example TMs to see what can be done.
