Iterative arrays with a wee bit alternation
Buchholz, Thomas; Klein, Andreas; Kutrib, Martin (1999)An iterative array is a line of interconnected interacting finite automata. One distinguished automaton, the communication cell, is connected to the outside world and fetches the input serially symbol by symbol. We are ... -
Iterative arrays with limited nondeterministic communication cell
Buchholz, Thomas; Klein, Andreas; Kutrib, Martin (1999)Iterative arrays with restricted nondeterminism are investigated. Non-determinism is provided for the distinguished communication cell only. All the other cells are deterministic ones. Moreover, the number of allowed ... -
Iterative arrays with small time bounds
Buchholz, Thomas; Klein, Andreas; Kutrib, Martin (1999)An iterative arrays is a line of interconnected interacting finite automata. One distinguished automaton, the communication cell, is connected to the outside world and fetches the input serially symbol by symbol. Sometimes ... -
On interacting automata with limited nondeterminism
Buchholz, Thomas; Klein, Andreas; Kutrib, Martin (1998)Oneway and twoway cellular language acceptors with restricted non determinism are investigated. The number of nondeterministic state transitions is regarded as limited resource which depends on the length of the input. ... -
On tally languages and generalized interacting automata
Buchholz, Thomas; Klein, Andreas; Kutrib, Martin (1999)Devices of interconnected parallel acting sequential automata are investigated from a language theoretic point of view. Starting with the wellknown result that each tally language acceptable by a classical oneway cellular ... -
On the power of one-way bounded cellular time computers
Buchholz, Thomas; Kutrib, Martin (1996)Comparisons of different cellular devices and the investigation of their computing power can be made in terms of their capabilities to timeconstruct and timecompute functions. Timeconstruction means that a distinguished ... -
On time computability of functions in one-way cellular automata
Buchholz, Thomas; Kutrib, Martin (1995)The capability of oneway (spacebounded) cellular automata (OCA) to timecompute functions is investigated. That means given an constant input of length n a distinguished cell has to enter a distinguished state exactly ... -
On time reduction and simulation in cellular spaces
Buchholz, Thomas; Klein, Andreas; Kutrib, Martin (1998)We prove a generalized and corrected version of the time reduction theorem for cellular spaces. One basic tool for investigations in this field is the concept of simulation between systems of automata. We propose a general ... -
One guess one-way cellular arrays
Buchholz, Thomas; Klein, Andreas; Kutrib, Martin (1998)Oneway cellular automata with restricted nondeterminism are investigated. The number of allowed nondeterministic state transitions is limited to a constant. It is shown that a limit to exactly one step does not decrease ... -
Real-time language recognition by alternating cellular automata
Buchholz, Thomas; Klein, Andreas; Kutrib, Martin (1999)The capabilities of alternating cellular automata (ACA) to accept formal languages are investigated. Several notions of alternation in cellular automata have been proposed. Here we study socalled nonuniform ACAs. Our ... -
Some relations between massively parallel arrays
Buchholz, Thomas; Kutrib, Martin (1996)Relations between various models for massively parallel computers are investigated. These are arrays of finitestate machines -- eventually augmented by pushdown storage -- operating synchronously. The architectures differ ...
