Faster Parameterized Algorithms Using Linear Programming
TL;DR: It is argued that combining previously known preprocessing rules with the most straightforward branching algorithm yields an O*(2.618k) algorithm for the problem, and a kernel is obtained for the standard parameterization of Vertex Cover with at most 2k − clog k vertices, simpler than previously known kernels achieving the same size bound.

Known algorithms on graphs of bounded treewidth are probably optimal
TL;DR: In this paper, the authors obtained lower bounds on the running time of algorithms for solving problems on graphs of bounded treewidth, and proved the results under the Strong Exponential Time Hypothesis of Impagliazzo and Paturi, assuming that SAT cannot be solved in (2 - ∈)nmO(1) time.

Complexity of consistent query answering in databases under cardinality-based and incremental repair semantics
TL;DR: In this paper, the authors considered the cardinality-based repair semantics for consistent query answering in a dynamic setting, where a consistent database is affected by a sequence of updates, which may make it inconsistent.

TL;DR: Algorithms for the propositional model counting problem #SAT utilize tree decompositions of certain graphs associated with the given CNF formula, including primal, dual, and incidence graphs.
