The study of such graphs is called graph theory. Engineers need to find planarity in a graph when, for example, they are designing a computer chip without a crossed wire.

Mathematicians have long sought to develop algorithms that can compare any two graphs. In practice, many ...

Graph theory is both an area of mathematics and an important tool in computer science. In this context, a graph can be illustrated by a diagram consisting of a number of points (nodes, vertices ...

This past October, as Jacob Holm and Eva Rotenberg were thumbing through a paper they’d posted a few months earlier, they realized they had been sitting on something big.. For decades computer ...

Graphs are relatively simple mathematical objects — abstract representations of networks — that arise frequently in physics, chemistry and computer science.

The theoretical computer scientist László Babai has retracted a claim that amazed the computer science community when he made it just over a year ago. In November 2015, he announced that he had come ...

Welcome to the website of the CS theory group at CU Boulder! Our faculty and students research all aspects of theoretical computer science, from core areas such as algorithms, complexity, and ...

Thus, in the language of graph theory, ... Science News was founded in 1921 as an independent, nonprofit source of accurate information on the latest news of science, ...
