A Combinatorial Algorithm for Pfaffians

The Pfaffian of an oriented graph is closely linked to
Perfect Matching. It is also naturally related to the determinant of
an appropriately defined matrix. This relation between Pfaffian and
determinant is usually exploited to give a fast algorithm for
computing Pfaffians.

We present the first completely combinatorial algorithm for ... more >>>

The polynomially bounded perfect matching problem is in NC^2

The perfect matching problem is known to
be in P, in randomized NC, and it is hard for NL.
Whether the perfect matching problem is in NC is one of
the most prominent open questions in complexity
theory regarding parallel computations.

Grigoriev and Karpinski studied the perfect matching problem
