Doom will be AI's next big gaming challenge

Competitors will tap machine learning and other techniques to create their bots

AI may have trounced humanity in the ancient game of Go, but it remains untested in countless other gaming arenas. Case in point: Doom, which, it turns out, will be the technology's next big challenge.

Launched in 1993, Doom is widely considered a landmark title in the video-game industry for popularizing the first-person shooter genre. Now, artificial-intelligence researchers will have a chance to pit their creations against others in a contest based on the game at the IEEE Computational Intelligence and Games conference in September.

To create their bots, competitors in the Visual Doom AI competition will use ViZDoom, a platform based on the game that's used for research in machine learning. Gaming AI bots typically have access to the game’s internal data, including maps, locations of objects, and positions of characters, but the bots in this contest will have only the raw visual input a human would.

Participants in the contest are allowed to use any technique to develop their bots, but machine-learning methods are encouraged because that's the focus of the ViZDoom platform.

There will be two competition tracks, according to the contest's website. The first is a limited deathmatch on a known map; in that case, rocket launchers are the only weapon available, though agents can gather medikits and ammo as well. The second track will be a full deathmatch on three unknown maps; two different maps will be provided for training.

Either way, each AI bot will be run on a separate machine with just a single CPU and GPU at its disposal. Bots will battle the other competitors for 10 minutes on a single map. Each game will be repeated 12 times for the limited deathmatch competition and four times for the full one. In each case, the bot with the most "frags" -- or opponents killed -- wins.

Results of the contest will be announced in late September. All submissions will be published after the competition is over.

Researchers are increasingly using games to test their AI, including also Minecraft. The strategy game StarCraft is widely considered a particularly daunting challenge.

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.
