Beyond Evolutionary Algorithms for Search-based Software Engineering

no code implementations27 Jan 2017 Jianfeng Chen, Vivek Nair, Tim Menzies

Context: Evolutionary algorithms typically require a large number of evaluations (of solutions) to converge - which can be very slow and expensive to evaluate. Objective: To solve search-based software engineering (SE) problems, using fewer evaluations than evolutionary methods. Method: Instead of mutating a small population, we build a very large initial population which is then culled using a recursive bi-clustering chop approach.
