Computational Life Reactor (Based on Brainfuck)

Computational Life Reactor (CLR) is an interactive browser implementation by Alex Borger of the computational-life experiments studied by Agüera y Arcas and collaborators https://arxiv.org/abs/2406.19108.

Random byte tapes are repeatedly paired and executed in the BFF language, allowing self-replicating programs to emerge without a fitness function or explicit selection process. CLR provides live population visualizations, frequency and compression measurements, and a step-by-step execution sampler. The simulation runs locally using WebAssembly and parallel browser workers.

A great 12 minutes introduction into the topic featuring CLR is provided by Johannes Martin (Number Cruncher) on YouTube https://youtu.be/w9_fWcNeITg
