URM Emulator

Le premier émulateur de URM pour Android!

URM Emulator for Android, is an Unlimited Register Machine implementation as defined in the book "Computability: An Introduction to Recursive Function Theory", by Nigel Cutland.

This emulator was conceived to be quick and pleasant for designing and debugging your URM programs, while maintaining a very low memory footprint even during extremelly long calculations with very large values.

Any feedback is greatly appreciated!

With this App you can:

✔ Design and run your programs.

✔ Set 6 different computation speeds (can be changed during the computation).

✔ Set a special high-performance mode, called "Realtime".

✔ Follow your program's execution closely with the URM state changes highlights.

✔ Save your programs for later use.

✔ Try out the 15 example programs that come with the app.

✔ Auto-save last computation (triggered by a Halt in the URM)

✔ Pause/Unpause or Halt computations at any time.

✔ Run your program step-by-step.

✔ Know the elapsed time and number of steps your algorithm is doing.

✔ Follow the Registers state recent history.

✔ Leave the app during a calculation, without loosing data.

✔ Monitor the background URM service state with the notification icon.

✔ Use values for registers up to 9.22 × 10^18.

✔Large Screen mode: Devices with 7 inch screens and larger, on landscape orientation, have a dedicated user interface that takes full advantage of the screen size, having a 3-parted screen, with 3 resizable windows.
