text: 'Efficiently parallelizable parameterized problems have been classified as
being either in the class FPP (fixed-parameter parallelizable) or the class PNC
(parameterized analog of NC), which contains FPP as a subclass. In this paper,
we propose a more restrictive class of parallelizable parameterized problems called
fixed-parameter parallel-tractable (FPPT). For a problem to be in FPPT, it should
possess an efficient parallel algorithm not only from a theoretical standpoint
but in practice as well. The primary distinction between FPPT and FPP is the parallel
processor utilization, which is bounded by a polynomial function in the case of
FPPT. We initiate the study of FPPT with the well-known k-vertex cover problem.
In particular, we present a parallel algorithm that outperforms the best known
parallel algorithm for this problem: using O(m) instead of O(n2) parallel processors,
the running time improves from 4logn+O(kk) to O(k⋅log3n), where m is the number
of edges, n is the number of vertices of the input graph, and k is an upper bound
of the size of the sought vertex cover. We also note that a few P-complete problems
fall into FPPT including the monotone circuit value problem (MCV) when the underlying
graphs are bounded by a constant Euler genus.'
