A Duality between Clause Width and Clause Density for SAT
We consider the relationship between the complexities of - and those of restricted to formulas of constant density. Let be the infimum of those such that - on variables can be dec...

Unified Definition of Heuristics for Classical Planning
In many types of planning algorithms distance heuristics play an important role. Most of the earlier works restrict to STRIPS operators, and their application to a more general lan...

Rounds in Communication Complexity Revisited
The k-round two-party communication complexity was studied in the deterministic model by [14] and [4] and in the probabilistic model by [20] and [6]. We present new lower bounds th...

Efficiently learning linear-linear exponential family predictive representations of state
Exponential Family PSR (EFPSR) models capture stochastic dynamical systems by representing state as the parameters of an exponential family distribution over a shortterm window of...

On the complexity of the multivariate Sturm-Liouville eigenvalue problem
We study the complexity of approximating the smallest eigenvalue of −∆ + q with Dirichlet boundary conditions on the d-dimensional unit cube. Here ∆ is the Laplacian, and th...
