A note on emptiness for alternating finite automata with a one-letter alphabet
We present a new proof of PSPACE-hardness of the emptiness problem for alternating finite automata with a singleton alphabet. This result was shown by Holzer (1995) who used a pr...

Descriptional Complexity of Machines with Limited Resources
: Over the last 30 years or so many results have appeared on the descriptional complexity of machines with limited resources. Since these results have appeared in a variety of diff...

Finding Lower Bounds for Nondeterministic State Complexity Is Hard
We investigate the following lower bound methods for regular languages: The fooling set technique, the extended fooling set technique, and the biclique edge cover technique. It is ...

Finding Cognate Groups Using Phylogenies
A central problem in historical linguistics is the identification of historically related cognate words. We present a generative phylogenetic model for automatically inducing cogn...
