Another type of local search is evolutionary computation , which aims to iteratively improve a set of candidate solutions by "mutating" and "recombining" them, selecting only the fittest to survive each generation. Distributed search processes can coordinate via swarm intelligence algorithms. Two popular swarm algorithms used in search are particle swarm optimization (inspired by bird flocking ) and ant colony optimization (inspired by ant trails ). Formal logic

5180-496: Was launched at Google by Sebastian Thrun, the former director of the Stanford Artificial Intelligence Laboratory (SAIL) and Anthony Levandowski , founder of 510 Systems and Anthony's Robots. The initial software code and artificial intelligence (AI) design of the effort started before the team worked at Google, when Thrun and 15 engineers, including Dmitri Dolgov, Mike Montemerlo, Hendrik Dahlkamp, Sven Strohband, and David Stavens , built Stanley and Junior, Stanford's entries in
5254-578: Was licensed by the Nevada Department of Motor Vehicles (DMV) in May 2012. The car was "driven" by Chris Urmson with Levandowski in the passenger seat. This was the first US license for a self-driven car. In January 2014 Google was granted a patent for a transportation service funded by advertising that included autonomous vehicles as a transport method. In late May, Google revealed an autonomous prototype , which had no steering wheel, gas pedal, or brake pedal. In December, Google unveiled
5328-899: Was not associated with Google. Within weeks Levandowski founded Anthony's Robots to do so. He retrofitted the car with light detection and ranging technology (lidar), sensors, and cameras. The Stanford team ( Stanley (vehicle) ) provided its code base to the project. The ensuing episode depicting Pribot delivering pizza across the San Francisco Bay Bridge under police escort aired in December 2008. The project success led Google to greenlight Google's self-driving car program in January 2009. In 2011, Google acquired 510 Systems (co-founded by Levandowski, Pierre-Yves Droz and Andrew Schultz), and Anthony's Robots for an estimated US$ 20 million. Levandowski's vehicle and hardware, and Stanford's AI technology and software, became
5402-508: Was set to kill its trucking program. In July 2024, Waymo began testing its sixth-generation robotaxis which are based on electric vehicles by Chinese automobile company Zeekr , developed in a partnership first announced in 2021. They were anticipated to reduce costs, at a time when Waymo was operating at a loss. In October 2024, Waymo closed a $ 5.6 billion funding round led by Alphabet, aimed at expanding its robotaxi services, bringing its total capital to over $ 11 billion. Around that time,
5476-755: Was the keynote speaker at the Annual STOA Lecture at the European Parliament. From 2020 to 2024 he was a member of the International Advisory Board of STOA (Panel for the Future of Science and Technology of the European Parliament). Artificial Intelligence Artificial intelligence ( AI ), in its broadest sense, is intelligence exhibited by machines , particularly computer systems . It
