The title is "How a Math Genius Hacked OK Cupid to Find True Love." There is no evidence in the story that the protagonist is a math genius, merely a doctoral candidate in math at UCLA. But it does describe, in reasonable detail, how he first data mined OK Cupid, a large dating site, and then used statistical techniques to analyze the data in order to figure out how to construct a profile that would attract women he was likely to find of interest—and do it without lying.
It took more than fifty dates to find one that worked. They are now engaged.
