(LaTeX) Abstract:
We describe the implementation of an $O(nm \log n)$ algorithm
for weighted matchings in general graphs. The algorithm is a variant of the
algorithm of Galil, Micali, and Gabow and requires the use of concatenable
priority queues. No previous implementation had a worst-case guarantee of
$O(nm \log n)$. We compare our implementation to the experimentally fastest
implementation (called Blossom IV) due to Cook and Rohe; Blossom IV is an
implementation of Edmonds' algorithm and has a running time no better than
$O(n^3)$. Blossom IV requires only very simple data structures.
Our experiments show that our new implementation is competitive
to Blossom IV.
