# What contributions has PPCG made to the fields of math or computer science?

Most of the content on PPCG involves clever applications of existing algorithms, or just-fast-enough-to-pass solutions to problems that supercomputers have found millions of answers/digits/etc to already. However, somewhere among all of the brainpower we spend on these challenges, surely someone has come up with something truly original.

Possible examples:

• a new good algorithm for a known problem
• establishing a new lower or upper bound for some value or some algorithm's runtime
• extending an existing OEIS sequence beyond previous computation

Where are those things?

• While not specifically maths or science related I believe those who post challenges get better at designing a technical brief. Jun 5 '15 at 14:41

• @wchargin for now the bar is pretty low, given that we've got just a dozen or so examples. Go ahead and add that to the "Appearances in papers and articles" answer. May 9 '16 at 17:59
