It is thus not possible to make a direct comparison of how individual algorithmic ideas affect the performance on different graph classes.\n  We present an algorithmic software framework that facilitates implementation of heuristics as independent extensions to a common core algorithm. It therefore becomes easy to perform a detailed comparison of the performance an","authors_text":"Daniel Merkle, Jakob L.
