Is using three tapes in a multitape TN equivalent to single tape time t2(square) or t3(cube)? In other words is the time complexity directly related to number of tapes?
Using three tapes in a multitape Turing machine (MTM) does not necessarily result in an equivalent time complexity of t2(square) or t3(cube). The time complexity of a computational model is determined by the number of steps required to solve a problem, and it is not directly related to the number of tapes used in the
If we have two TMs that describe a decidable language is the equivalence question still undecidable?
In the field of computational complexity theory, the concept of decidability plays a fundamental role. A language is said to be decidable if there exists a Turing machine (TM) that can determine, for any given input, whether it belongs to the language or not. The decidability of a language is a crucial property, as it
In the case of detecting the start of the tape, can we start by using a new tape T1=$T instead of shifting to the right?
In the field of computational complexity theory and Turing machine programming techniques, the question of whether we can detect the start of a tape by using a new tape T1=$T instead of shifting to the right is an interesting one. To provide a comprehensive explanation, we need to delve into the fundamentals of Turing machines
Are there current methods for recognizing Type-0? Do we expect quantum computers to make it feasible?
Type-0 languages, also known as recursively enumerable languages, are the most general class of languages in the Chomsky hierarchy. These languages are recognized by Turing machines that can accept or reject any input string. In other words, a language is Type-0 if there exists a Turing machine that halts and accepts any string in the

What is the main difference between linear bounded automata and Turing machines?
Linear bounded automata (LBA) and Turing machines (TM) are both computational models used to study the limits of computation and the complexity of problems. While they share similarities in terms of their ability to solve problems, there are fundamental differences between the two. The main difference lies in the amount of memory they have access
