[HTML][HTML] The isomorphism problem for k-trees is complete for logspace

V Arvind, B Das, J Köbler, S Kuhnert - Information and Computation, 2012 - Elsevier
We show that, for k constant, k-tree isomorphism can be decided in logarithmic space by
giving an O (klogn) space canonical labeling algorithm. The algorithm computes a unique …

Formal theories for linear algebra

SA Cook, LA Fontes - Logical Methods in Computer Science, 2012 - lmcs.episciences.org
We introduce two-sorted theories in the style of [CN10] for the complexity classes\oplusL and
DET, whose complete problems include determinants over Z2 and Z, respectively. We then …

The complexity of the comparator circuit value problem

SA Cook, Y Filmus, DTM Le - arXiv preprint arXiv:1208.2721, 2012 - arxiv.org
In 1990 Subramanian defined the complexity class CC as the set of problems log-space
reducible to the comparator circuit value problem (CCV). He and Mayr showed that …

[PDF][PDF] Parallel algorithms for the maximal independent set problem in graphs

L Barba - School of Computer Science Carleton university …, 2012 - cglab.ca
In this paper we describe the randomized parallel algorithm proposed by Blelloch et

[PDF][PDF] LITERATURE REVIEW: Parallel algorithms for the maximal independent set problem in graphs

L Barba - 2012 - cglab.ca
Let G=(V, E) be an undirected graph. An independent set of G is a subset I of V such that no
two vertex in I are adjacent in G. A Maximal Independent Set (MIS) of G is an independent …

A circuit uniformity sharper than DLogTime

G Bonfante, V Mogbil - 2012 - hal.science
We consider a new notion of circuit uniformity based on the concept of rational relations,
called Rational-uniformity and denoted Rat. Our goal is to prove it is sharper than DLogTime …
