# A new algebraic approach to the graph isomorphism and clique problems

## TL;DR

This paper introduces algebraically entangled polynomial-time algorithms for the graph isomorphism and clique problems, whose correctness remains to be empirically verified or proven, highlighting a novel algebraic approach to these classic NP problems.

## Contribution

It presents new algebraic algorithms for graph isomorphism and clique problems that are polynomial-time but whose correctness is yet to be established.

## Key findings

- Algorithms are polynomial-time but unproven in correctness.
- Approach emphasizes algebraic entanglement in data processing.
- Potential implications for understanding NP-complete problems.

## Abstract

As it follows from G\"odel's incompleteness theorems, any consistent formal system of axioms and rules of inference should imply a true unprovable statement. Actually, this fundamental principle can be efficiently applicable in computational mathematics and complexity theory concerning the computational complexity of problems from the class NP, particularly and especially the NP-complete ones. While there is a wide set of algorithms for these problems that we call heuristic, the correctness or/and complexity of each concrete algorithm (or the probability of its correct and polynomial-time work) on a class of instances is often too difficult to determine, although we may also assume the existence of a variety of algorithms for NP-complete problems that are both correct and polynomial-time on all the instances from a given class (where the given problem remains NP-complete), but whose correctness or/and polynomial-time complexity on the class is impossible to prove as an example for G\"odel's theorems. However, supposedly such algorithms should possess a certain complicatedness of processing the input data and treat it in a certain algebraically "entangled" manner. The same algorithmic analysis in fact concerns all the other significant problems and subclasses of NP, such as the graph isomorphism problem and its associated complexity class GI. The following short article offers a couple of algebraically entangled polynomial-time algorithms for the graph isomorphism and clique problems whose correctness is yet to be determined either empirically or through attempting to find proofs. The authors are grateful to Prof. Anuj Dawar (University of Cambridge) for kindly endorsing the present article for publishing in arXiv.
