Reversal-Bounded Counter Machines Revisited

چکیده
We extend the class of reversal-bounded counter machines by authorizing a finite number of alternations between increasing and decreasing mode over a given bound. We prove that extended reversal-bounded counter machines also have effective semi-linear reachability sets. We also prove that the property of being reversal-bounded is undecidable in general even when we fix the bound, whereas this problem becomes decidable when considering Vector Addition System with States.

متن کاملDense-choice Counter Machines revisited
This paper clarifies the picture about Dense-choice Counter Machines, which have been less studied than (discrete) Counter Machines. We revisit the definition of ”Dense Counter Machines” so that it now extends (discrete) Counter Machines, and we provide new undecidability and decidability results. Using the first-order additive mixed theory of reals and integers, we give a logical characterizat...
متن کاملOne-Reversal Counter Machines and Multihead Automata: Revisited
We investigate the power of (1-reversal) counter machines (finite automata with multiple counters, where each counter can ‘‘reverse’’ only once, i.e., once a counter decrements, it can no longer increment) and one-way multihead finite automata (finite automata with multiple one-way input heads) as a language acceptor. They can be non-deterministic as well as augmented with a pushdown stack. Fir...
متن کاملDeletion Operations on Deterministic Families of Automata
Many different deletion operations are investigated applied to languages accepted by one-way and twoway deterministic reversal-bounded multicounter machines, deterministic pushdown automata, and finite automata. Operations studied include the prefix, suffix, infix and outfix operations, as well as left and right quotient with languages from different families. It is often expected that language...
متن کاملWhen Model-Checking Freeze LTL over Counter Machines Becomes Decidable
We study the decidability status of model-checking freeze LTL over various subclasses of counter machines for which the reachability problem is known to be decidable (reversal-bounded counter machines, vector additions systems with states, flat counter machines, one-counter machines). In freeze LTL, a register can store a counter value and at some future position an equality test can be done be...
