Game-playing AI has found solutions to some versions of poker. But heads-up, no-limit Texas Hold’em represents an especially complex challenge with 10160 possible plays at different stages of the game (possibly more than the number of atoms in the universe). Such complexity exists because this two-player version of poker allows for unrestricted bet sizes. To deal with such a game, many AI rely on a technique called counterfactual regret minimization (CFR). Typical CFR algorithms try to solve games such as poker through several steps at each decision point. First, they come up with counterfactual values representing different game outcomes. Second, they apply a regret minimization approach to see which strategy leads to the best outcome. And third, they typically average the most recent strategy with all past strategies.

ATLASSIAN CO-FOUNDER MIKE Cannon-Brookes describes Trello as a simple online application. But simple doesn’t have to mean cheap: His company just agreed to acquire the web-based project management app for $425 million—a ridiculous-sounding amount of money that may well be worth paying. “Simple products can be deceptive in their simplicity,” Cannon-Brookes says.

Our team at USC has conducted the largest analyses1 of STEM depictions in motion pictures to date. We examined 129 G-, PG-, and PG-13-rated top-grossing films from 2006 to 2011. Only 26 females with STEM jobs were depicted on screen across 5,839 speaking characters. Of those 26 females, consider the following disturbing trends: Only three were African-American—two in life or physical sciences, one engineer. Only one woman was depicted as a mathematician. She was white, shown in a low-cut, tight-fitting Santa suit, and was shown estimating the production time for toys on the North Pole’s assembly line. This problem goes beyond American films. In a follow-up study, we assessed 120 movies released between 2010 and 2013 in 10 top international film markets. Out of 5,799 characters, 121 held a STEM job. Of these characters, only 14 were female and there were no mathematicians. No females in STEM were African-American.
