👉 Learn how to determine the extrema, the intervals of increasing/decreasing, and the concavity of a function from its graph. The extrema of a function are the points where the graph changes from ...

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 ...

Distinguishing properties in graph theory encompass a suite of concepts and invariants designed to quantify and break symmetries in graphs by means of labellings or colourings. At the heart of this ...
