For the operational state complexity of deterministic input-driven multi-counter automata under Boolean operations, tight bounds on the number of states are established. It is shown that a nondeterministic device can be determinized and that 2 n − 1 is a necessary and sufficient blow-up in the number of states for the determinization. Finally, we study descriptional complexity aspects of input-driven multi-counter automata. For k ≥ 2 counters, the decidability problems of emptiness, finiteness, universality, inclusion, equivalence, regularity, and context-freeness are shown to be non-semidecidable. For input-driven multi-counter automata with 0 or 1 counter, we discuss the computational complexity of their decidable problems. Just create an account in a few seconds, and you are done.
Create a Shared Counter - Clicking on this will let you create a counter that can be shared across multiple devices. Furthermore, we investigate the closure properties of the language families. Settings: Go to the Singular Counter - Clicking this button will launch a counter that is on your device only and is not shared or synced. The hierarchy interestingly collapses at the level of the bound.

This means that any input alphabet induces an upper bound which depends on the alphabet size only, such that k + 1 counters are more powerful than k counters as long as k is less than this bound. This is part of the Unit Operations course.
MULTI COUNTER HOW TO
In addition, it is possible to prove a proper counter hierarchy depending on the alphabet size. Discover how to solve and understand the multi-stage counter-current extraction process. We study the computational power of the resulting language families and compare them with known language families inside the Chomsky hierarchy. On such devices, the input letters uniquely determine the operations on the underlying data structure that is consisting of multiple counters.
MULTI COUNTER PRO
The model of deterministic input-driven multi-counter automata is introduced and studied. Multi Counter Pro allows to count a discrete number of elements of different kinds in a single screen using your iPhone or iPad to avoid any error.
