Since the 1970s, algorithms have been able to test graph isomorphism, but in exponential time. This means that the increasing complexity of the graphs increased the algorithm's running time ...

Most problems can be solved by many different algorithms, each with its own demands on time and space. Complexity theorists sort problems into categories, called complexity classes, based on the ...

Google stands firm in its position that the changes will be a benefit to the web, and changes to the Search algorithm are just the start. Last week, Google CEO Sundar Pichai stood in front of a ...
