Can a turing machine move the head over the tape by more than one cell at each step of their operation
A Turing machine, as originally conceived by Alan Turing in 1936, operates on a tape divided into discrete cells, each capable of holding a symbol from a finite alphabet. The machine has a head that can read and write symbols on the tape and move left or right one cell at a time. This fundamental

Can a turing recognizable language form a subset of decidable language?
To address the question of whether a Turing recognizable language can form a subset of a decidable language, it is essential to consider the fundamental concepts of computational complexity theory, particularly focusing on the classifications of languages based on their decidability and recognizability. In computational complexity theory, languages are sets of strings over some alphabet,
Can a star and union operator bind tighter than the concatenation operator in regular expression?
In the domain of regular expressions within the context of formal languages and automata theory, understanding the precedence and binding of operators is important for correctly interpreting and constructing expressions. Regular expressions are a powerful tool for defining patterns in strings, and they are widely used in various fields, including computer science, linguistics, and cybersecurity.

Can a problem be in NP complexity class if there is a non deterministic turing machine that will solve it in polynomial time
The question "Can a problem be in NP complexity class if there is a non-deterministic Turing machine that will solve it in polynomial time?" touches upon fundamental concepts in computational complexity theory. To address this question comprehensively, we must consider the definitions and characteristics of the NP complexity class and the role of non-deterministic Turing
Can a language be turing decidable if there exist enumerator that enumerates it?
In the field of computational complexity theory, particularly when discussing Turing machines and enumerators, it is essential to understand the concepts of decidability and enumerability. To address the question of whether a language can be Turing decidable if there exists an enumerator that enumerates it, we must consider the definitions and relationships between these concepts.
Can a DFSM repeat without any randomness?
A Deterministic Finite State Machine (DFSM), also known as a Deterministic Finite Automaton (DFA), is a fundamental concept in the field of computational theory and automata. It is a theoretical machine used to recognize regular languages, which are sets of strings defined by specific patterns. A DFSM consists of a finite number of states, including
What is perfect repeatability in DFSM
Perfect repeatability in the context of Deterministic Finite State Machines (DFSMs) refers to the property whereby the machine consistently produces the same output for a given input sequence, regardless of how many times the input sequence is processed. This concept is fundamental to the design and analysis of DFSMs, as it ensures that the behavior
