Minor-Free Graph: A graph that does not contain a specified smaller graph (minor) as a subgraph, which is critical for certifying graph classes and in achieving computational optimisations.

AI is the most disruptive technology of our lifetimes, and AI chips are the most disruptive infrastructure for AI. By that measure, the impact of what Graphcore is about to massively unleash in ...

Computational complexity measures how much work is required to solve different problems. It provides a useful classification tool for OR/MS practitioners, especially when tackling discrete ...

In computational complexity theory, P and NP are two classes of problems. P is the class of decision problems that a deterministic Turing machine can solve in polynomial time. In useful terms… ...

Physics Mathematicians who unravelled computational complexity win Abel prize By Timothy Revell 17 March 2021 László Lovász (left) and Avi Wigderson (right) have been awarded the Abel prize ...

He then uses graph theory to prove that any game exhibiting both location traversal and single-use paths is NP-hard, that’s the same class of complexity as the travelling salesman problem.
