Game of Life
In the associated Python file, you can run the Game of Life, written in Concrete Python.

Installation
In addition to Concrete, you must install pygame
in your virtual environment:
pip3 install pygame
Once done, if you go to frontends/concrete-python/examples/game_of_life
, python game_of_life.py --help
should give you the manpage:
Game of Life in Concrete Python.
options:
-h, --help show this help message and exit
--dimension DIMENSION
Dimension of the grid
--refresh_every REFRESH_EVERY
Refresh the grid every X steps
--method {method_3b,method_4b,method_5b,method_basic}
Method for refreshing the grid
--log2_global_p_error LOG2_GLOBAL_P_ERROR
Probability of correctness issue (full circuit)
--log2_p_error LOG2_P_ERROR
Probability of correctness issue (individual TLU)
--simulate Simulate instead of running computations in FHE
--show_mlir Show the MLIR
--stop_after_compilation
Stop after compilation
--text_output Print a text output of the grid
Running
Then, you can play with the different options, and in particular:
dimension
, to chose the size of the grid; the larger, the slowermethod
, to chose which implementation is used for the grid updatelog2_global_p_error
andlog2_p_error
, to chose the probability of correctness (see the Concrete documentation for more information)simulate
, to do computations only in simulation, i.e., not in FHE
Typical Executions
In simulation: python3 game_of_life.py --dimension 100 --refresh_every 50 --simulate
In FHE: python3 game_of_life.py --dimension 6 --refresh_every 8 --log2_p_error -40 --method method_4b
Technical Explanations
A blog is currently in the process of being written, and a link will be added here when it's available. In the meantime, some explanations are given in the code.
