Hamiltonian index is NP-complete
In this paper we show that the problem to decide whether the hamiltonian index of a given graph is less or equal to a given constant is ∗ Research supported by grants No. 1M0545...

Equivalence of Labeled Markov Chains
We consider the equivalence problem for labeled Markov chains (LMCs), where each state is labeled with an observation. Two LMCs are equivalent if every finite sequence of observat...

Small Clique Detection and Approximate Nash Equilibria
Recently, Hazan and Krauthgamer showed [12] that if, for a fixed small ε, an ε-best ε-approximate Nash equilibrium can be found in polynomial time in two-player games, then it ...
