One computer scientist’s “stunning” proof is the first progress in 50 years on one of the most famous questions in computer ...

A puzzle that has long flummoxed computers and the scientists who program them has suddenly become far more manageable. A new algorithm efficiently solves the graph isomorphism problem, computer ...

Refining with colors. Mathematicians have developed various strategies to compare graphs. Since the 1970s, algorithms have been able to test graph isomorphism, but in exponential time.

An analogous complexity class for space is dubbed “PSPACE.” The relationship between these two classes is one of the central questions of complexity theory. Every problem in P is also in PSPACE, ...

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.

The intersection of the PLS and PPAD classes itself forms a class of problems known as PLS int PPAD. It contains many natural problems relevant to complexity researchers. However, until now, ...

A project headed by the SEI’s Scott McMillan took a step in 2020 toward standardizing graph algorithm application development in C++.

The algorithm involves a hierarchy of classes, parts of physical objects, and subroutines. The loops of these graphs are eliminated by replacing each by a single “equivalence class” node.

One of the first algorithms for this is Jarník’s algorithm, by Czech mathematician Vojtěch Jarník in 1930. Later this was rediscovered by Robert C. Prim in 1957 and in 1956 by Edsger W ...
