Multi-purpose extensible self-adaptive optimizer and fuzzer

Project description

Byron is an evolutionary tool: given a problem, it first generates a set of random solutions, then iteratively refines and improves them using the results of their evaluations together with structural information. It may be used as a coverage-driven fuzzer and a general-purpose optimizer.

Byron encodes candidate solutions as directed multigraphs and can produce quite complex, highly structured results, such as a realistic program with loops, interrupts, and recursive subroutines.

Candidate solutions are evaluated by calling a user Python function or a shell script, that, for instance, may use proprietary tools. Different types of parallelization are supported out of the box, from simple multithreading to the creation of temporary directories where multiple subprocesses are concurrently spawned.

Installation

⚠️ Byron is currently in pre-alpha and under active development

pip install --upgrade byron

Few optional dependencies can enhance Byron, but are not strictly required:

pip install --upgrade matplotlib
pip install --upgrade joblib
pip install --upgrade psutil
