Insertion operations on deterministic reversal-bounded counter machines

作者:

Highlights:

• Insertions on deterministic reversal-bounded multicounter machines (DCM) are studied.

• DCMs with 2 counters are not closed under right concatenation with the universe.

• For left concatenation, only 1 counter that makes 1 reversal is needed for non-closure.

• The right input end-marker is necessary for DCM as opposed to deterministic pushdowns.

• DCM is closed under inverse deterministic transducers augmented by counters.
