Cubic regularization of Newton method and its global performance
In this paper, we provide theoretical analysis for a cubic regularization of Newton method as applied to unconstrained minimization problem. For this scheme, we prove general local...

Implicit characterizations of FPTIME and NC revisited
Various simplified or improved, and partly corrected well-known implicit characterizations of the complexity classes FPTIME and NC are presented. Primarily, the interest is in si...

Evaluation of the distance spectrum of variable-length finite-state codes
The class of variable-length finite-state joint source-channel codes is defined and a polynomial complexity algorithm for the evaluation of their distance spectrum presented. Issu...

Pure Nash equilibria: complete characterization of hard and easy graphical games
We consider the computational complexity of pure Nash equilibria in graphical games. It is known that the problem is NP-complete in general, but tractable (i.e., in P) for special...

One-Way Permutations, Interactive Hashing and Statistically Hiding Commitments
We present a lower bound on the round complexity of a natural class of black-box constructions of statistically hiding commitments from one-way permutations. This implies a Ω( n ...
