#BrainFast
My take on an optimising interpreter for brainf*ck.
Here's some of BrainFast's times for some common benchmark brainf*ck programs, ran on my old laptop (2.2 GHz Intel Core i7, 8gbs of ram), where times are an average of 10.
| Program | Time (sec) |
|---|---|
| Mandel.b | 6.385 |
| Hanoi.b | 0.292 |
| Long.b | 1.488 |
These times put it comfortably in 3rd place in the very prestigious and rigorous competition of "Fastest BF Interpreters I Could Find".
For a comparison of times for these programs run in the more well-known interpreters see: https://esolangs.org/wiki/User:David.werecat/BFBench
Make sure to compile with optimisation for the best results.
g++ -O3 -march=native -std=c++11 -o brainf brainfast.cpp
time ./brainf < file.bf
Todo: Write about optimising techniques used.
