Can virtual machines be considered as FSMs?
The inquiry into whether virtual machines (VMs) can be considered finite state machines (FSMs) is an insightful question rooted in the intersection of computational models and system abstraction. To address this, it is appropriate to rigorously define both concepts, examine their respective theoretical underpinnings, and evaluate the extent to which their properties and operational semantics

Is algorithmically computable problem a problem computable by a Turing Machine accordingly to the Church-Turing Thesis?
The Church-Turing Thesis is a foundational principle in the theory of computation and computational complexity. It posits that any function which can be computed by an algorithm can also be computed by a Turing machine. This thesis is not a formal theorem that can be proven; rather, it is a hypothesis about the nature of

Can we can prove that Np and P class are the same by finding an efficient polynomial solution for any NP complete problem on a deterministic TM?
The question of whether the classes P and NP are equivalent is one of the most significant and long-standing open problems in the field of computational complexity theory. To address this question, it is essential to understand the definitions and properties of these classes, as well as the implications of finding an efficient polynomial-time solution

Can a turing machine decide and recognise a language and also compute a function?
A Turing machine (TM) is a theoretical computational model that plays a central role in the theory of computation and forms the foundation for understanding the limits of what can be computed. Named after the British mathematician and logician Alan Turing, the Turing machine is an abstract device that manipulates symbols on a strip of

Can a tape be limited to the size of the input (which is equivalent to the head of the turing machine being limited to move beyond the input of the TM tape)?
The question of whether a tape can be limited to the size of the input, which is equivalent to the head of a Turing machine being restricted from moving beyond the input on the tape, delves into the realm of computational models and their constraints. Specifically, this question touches upon the concepts of Linear Bounded
Are all languages Turing recognizable?
The question of whether all languages are Turing recognizable is a fundamental one in the field of computational complexity theory and the theory of computation.
