# Computational complexity theory and R (complexity)

## Difference between Computational complexity theory and R (complexity)

### Computational complexity theory vs. R (complexity)

Computational complexity theory is a branch of the theory of computation in theoretical computer science and mathematics that focuses on classifying computational problems according to their inherent difficulty, and relating those classes to each other. In computational complexity theory, R is the class of decision problems solvable by a Turing machine, which is the set of all recursive languages.

## Similarities between Computational complexity theory and R (complexity)

Computational complexity theory and R (complexity) have 2 things in common (in Unionpedia): Decision problem, Turing machine.

### Decision problem

In computability theory and computational complexity theory, a decision problem is a question in some formal system with a yes-or-no answer, depending on the values of some input parameters.

### Turing machine

A Turing machine is an abstract "machine" that manipulates symbols on a strip of tape according to a table of rules; to be more exact, it is a mathematical model that defines such a device.

### The list above answers the following questions

• What Computational complexity theory and R (complexity) have in common
• What are the similarities between Computational complexity theory and R (complexity)

## Computational complexity theory and R (complexity) Comparison

Computational complexity theory has 158 relations, while R (complexity) has 6. As they have in common 2, the Jaccard index is 1.22% = 2 / (158 + 6).
