A formal language is a set of strings over an alphabet, defined by precise rules. It's crucial in computer science…
A function computable by a Turing machine, representing the theoretical limit of what can be calculated. It forms the basis…
A cornerstone of computable function theory, the S-M-N theorem offers a way to create specific computable functions from general ones,…
A semi-decidable theory allows for an algorithm to list all its theorems. However, it may not offer a way to…
A computation is register computable if it can be performed by a register machine. This concept is fundamental in theoretical…
The recursion theorem, fundamental in computability theory, allows a function to call itself. It has significant implications in computer science,…
NP (Nondeterministic Polynomial time) is a complexity class for decision problems where a 'yes' answer can be quickly verified by…
A theoretical computational model where each step allows multiple choices, enabling simultaneous exploration of various execution paths. It's fundamental in…
NP is a complexity class for decision problems. A 'yes' answer can be verified in polynomial time by a deterministic…
Minimization is a core operation in recursive function theory, crucial for finding the smallest witness that satisfies a decidable predicate.…
