In this case, a meaningless but huge stream of pseudorandom data was beamed over 13km of coiled fibre optic cable in a lab setting.

What Verstraete and Mubayi discovered was that sampling from pseudorandom graphs frequently gives better bounds on Ramsey numbers than random graphs.

"It turned out that the pseudorandom graph we needed could be found in finite geometry," Verstraete stated.

Once they had the pseudorandom graph in place, they still had to puzzle out several pieces of math.

Together they discovered that pseudorandom graphs could advance the current knowledge on these old problems.
