This report summarizes the Fifth Workshop on Programming Languages and Operating Systems (PLOS 2009), which was held in conjunction with the SOSP 2009 conference. This report pres...
We consider the Edit distance with moves on the class of words and the class of ordered trees. We first exhibit a simple tester for the class of regular languages on words and gen...
In philosophy, the term ontology has been used since the 17th century to refer both to a philosophical discipline (Ontology with a capital "O"), and as a domain-independe...
We study the worst case complexity of regular operations on cofinite languages (i.e., languages whose complement is finite) and provide algorithms to compute efficiently the result...
We show that if a language L has a 4-round, black-box, computational zero-knowledge proof system with negligible soundness error, then ¯L ∈ MA. Assuming the polynomial hierarch...
