"Resistant" Polynomials and Stronger Lower Bounds for Depth-Three Arithmetical Formulas
We derive quadratic lower bounds on the ∗-complexity of sum-of-products-of-sums (ΣΠΣ) formulas for classes of polynomials f that have too few partial derivatives for the techn...

Finding Equilibria in Games of No Chance
Abstract. We consider finding maximin strategies and equilibria of explicitly given extensive form games with imperfect information but with no moves of chance. We show that a max...

Seed-Based Exclusion Method for Non-coding RNA Gene Search
Given an RNA family characterized by conserved sequences and folding constraints, the problem is to search for all the instances of the RNA family in a genomic database. As seed-ba...

Algorithms for Core Stability, Core Largeness, Exactness, and Extendability of Flow Games
In this paper, we give linear time algorithms to decide core stability, core largeness, exactness, and extendability of flow games on uniform networks (all edge capacities are 1)....

On the Number of Cycles in Planar Graphs
We investigate the maximum number of simple cycles and the maximum number of Hamiltonian cycles in a planar graph G with n vertices. Using the transfer matrix method we construct a...
