NP-completeness of generalized multi-Skolem sequences
A Skolem sequence is a sequence a1, a2, . . . , a2n (where ai ∈ A = {1, . . . , n}), each ai occurs exactly twice in the sequence and the two occurrences are exactly ai position...

Text Chunking based on a Generalization of Winnow
This paper describes a text chunking system based on a generalization of the Winnow algorithm. We propose a general statistical model for text chunking which we then convert into ...

Convergence Theorems for Generalized Random Variables and Martingales
We examine generalizations of random variables and martingales. We prove a new convergence theorem for setvalued martingales. We also generalize a well known characterization of se...

Generalizations of Blom And Bloem's PDF decomposition for permutation-invariant estimation
Minimum mean squared error estimates generally are not optimal in terms of a common track error statistic used in tracking benchmarks, namely a form of the Mean Optimal Subpattern...

General floorplan for reversible quantum-dot cellular automata
This paper presents the Collapsed Bennett Layout, a general purpose floorplan for reversible quantum-dot cellular automata (QCA) circuits. In order to exploit the full density and...
