byron 0.1.dev12

Multi-purpose extensible self-adaptive optimizer and fuzzer

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.
