Verifying Unboundedness via Amalgamation
Ashwani Anand, Sylvain Schmitz, Lia Schütze +1
Well-structured transition systems (WSTS) are an abstract family of systems that encompasses a vast landscape of infinite-state systems. By requiring a well-quasi-ordering (wqo) on…
Coverability in VASS Revisited: Improving Rackoff's Bound to Obtain Conditional Optimality
Marvin Künnemann, Filip Mazowiecki, Lia Schütze +2
Seminal results establish that the coverability problem for Vector Addition Systems with States (VASS) is in EXPSPACE (Rackoff, '78) and is EXPSPACE-hard already under unary encodi…
Unboundedness problems for machines with reversal-bounded counters
Pascal Baumann, Flavio D'Alessandro, Moses Ganardi +4
We consider a general class of decision problems concerning formal languages, called ``(one-dimensional) unboundedness predicates'', for automata that feature reversal-bounded coun…
