Abstract: Graphs are among the most ubiquitous models of both natural and human-made structures. They can be used to model many types of relations and process dynamics in computer science, physical, ...

A new algorithm efficiently solves the graph isomorphism problem, computer scientist László Babai announced November 10 at a Combinatorics and Theoretical Computer Science seminar at the ...

Rather than produce one example of how the model does not satisfy a given property, why not produce all of them at once? We call the set of all counterexamples a scenario graph. For a traditional use ...

Since then, said Josh Grochow, a computer scientist at the University of Colorado ... If a pharmacologist wanted to model drug interactions, for example, graph theory might show how two drugs respond ...

Dr Noam Zeilberger’s most recently published paper, ‘A theory of linear typings as flows on 3-valent graphs’, grew ‘unexpectedly ... the 33rd Annual ACM/IEEE Symposium on Logic in Computer Science ...

This example generates a simple drill-down bar chart that shows the regional sales figures for three sales regions. When the bar chart is displayed in a browser, you can select any one of the bars to ...

For example, a puzzle could have nine letters, shapes, or colors instead of numbers. When graph theorists label ... and that it has only one solution. Science News sponsorship position.
