We consider the use of state elimination to construct shorter regular expressions from finite-state automata. Although state elimination is an intuitive method for computing regul...
Abstract. We investigate a general paradigm for constructing arbitraryinput-length (AIL) MACs from fixed-input-length (FIL) MACs, define the waste as the relevant efficiency para...
Abstract. We study – within the framework of propositional proof complexity – the problem of certifying unsatisfiability of CNF formulas under the promise that any satisfiabl...
Program slicing is a program transformation that is useful in program debugging, program maintenance, and other applications that involve understanding program behavior. Given a p...
Techniques based on sums of squares appear promising as a general approach to the universal theory of reals with addition and multiplication, i.e. verifying Boolean combinations of...
