Consolidating LAMA with Best-First Width Search

Corrêa, Augusto B., Seipp, Jendrik

arXiv.org Artificial Intelligence

One key decision for heuristic search algorithms is how to balance exploration and exploitation. In classical planning, novelty search has come out as the most successful approach in this respect. The idea is to favor states that contain previously unseen facts when searching for a plan. This is done by maintaining a record of the tuples of facts observed in previous states. Then the novelty of a state is the size of the smallest previously unseen tuple. The most successful version of novelty search is best-first width search (BFWS), which combines novelty measures with heuristic estimates. An orthogonal approach to balance exploration-exploitation is to use several open-lists. These open-lists are ordered using different heuristic estimates, which diversify the information used in the search. The search algorithm then alternates between these open-lists, trying to exploit these different estimates. This is the approach used by LAMA, a classical planner that, a decade after its release, is still considered state-of-the-art in agile planning. In this paper, we study how to combine LAMA and BFWS. We show that simply adding the strongest open-list used in BFWS to LAMA harms performance. However, we show that combining only parts of each planner leads to a new state-of-the-art agile planner.


Pushing Buttons: The Fallout series doesn't just look right – it feels like it was made by gamers, too

The Guardian

I am a few episodes from the end of the series Fallout on Prime Video. In other words, it's just like the games, which veer between quiet, tragic moments exploring the vestiges of America, and being chased down a hill by irradiated scorpions because you've run out of ammo. Fallout's ensemble cast – with Walton Goggins' almost-immortal ghoul and Ella Purnell's wide-eyed vault-dweller the standouts – lets it cleverly compartmentalise the different aspects of the games' personality. As its director Jonathan Nolan pointed out, when I interviewed him last week alongside Bethesda's Todd Howard (the director of the games), this is a common device in TV storytelling but rare in games. Grand Theft Auto V does it successfully: each of the three protagonists represented a different part of GTA's DNA (Trevor the violent chaos, Michael the prestige crime drama, Franklin the Compton realism). But in most games we play one character, and we know them intimately by the end – or we get to shape them, and they become unique to us.


The Superhero Movie Is Dying. Its Replacement Is Waiting in the Wings.

Slate

For more than a decade, blockbuster comic book adaptations reliably clobbered all competition at the box office. Disney and HBO Max built their streaming strategies around intellectual property from Marvel and DC Comics. The studios turned this pulpy source material into a profusion of interconnected films and series that consistently drove ticket sales and subscriptions--until they didn't. Lately, serious superhero fatigue seems to have set in. Comic book movies regularly tank these days, and not just the ones based on second-string characters like Blue Beetle and Madame Web.


'Fallout' Nails Video Game Adaptations by Making the Apocalypse Fun

WIRED

For decades, it seemed like Hollywood couldn't get a video game adaptation right. Movies like Double Dragon, Super Mario Bros., and Lara Croft: Tomb Raider were all critically panned, with their creators called out for either sticking too close to the source material, failing to capture the magic of the games, or casting actors who didn't really embrace the films' inherent campiness. In recent years, though, there's been a shift in game adaptations, with projects like The Last of Us and Werewolves Within achieving critical acclaim and--in the case of the former, at least--a boatload of awards nods. You could point to a number of reasons to try to explain why game adaptations are getting better (Pedro Pascal, for example), but Jonathan Nolan, co-creator of Amazon Prime Video's new series Fallout, says he thinks it's because games often have "more sophisticated, more interesting, and more daring" storytelling than is often found in film or TV. When Nolan first started playing Fallout 3 in 2009, while trying to write The Dark Knight Rises, he was taken aback.


AI ranks EVERY Christopher Nolan movie - after director took home first-ever Oscar for Oppenheimer... so do YOU agree with ChatGPT?

Daily Mail - Science & tech

'Oppenheimer' swept away the competition at the 2024 Oscars, receiving seven awards including earning renowned director Christopher Nolan his first golden man statuette. While this is the filmmaker's first major award-winning film, he has been producing movies since 1998 when he made Following - and has made 10 more since. We asked ChatGPT to rank his other 11 films dating back to 26 years to the'Following' and 2010 film'Inception' up through his his 2012 film'The Dark Knight Rises' and his 2020 film'Tenet.' Renowned director Christopher Nolan took home his first Oscar for his critically acclaimed film, ' Oppenheimer.' The historic film starred Cillian Murphy as J Robert Oppenheimer, the director of the Los Alamos lab that designed and built the world's first atomic bomb during World War II - he is often known as the'father of the atomic bomb' Oppenheimer swept the box office when it was released on July 21, 2023, reeling in a whopping 82.4 million in opening weekend, winning Nolan Best Picture and Best Director during Sunday's award show.


At the "Oppenheimer" Oscars, Hollywood Went in Search of Lost Time

The New Yorker

This wasn't the first year that the Academy Awards fell on the second Sunday in March, forcing the good citizens of Hollywood to manage their hair appointments and limousine pickups around the annual scourge that is daylight-saving time. Even so, the ninety-sixth annual Oscars ceremony wrought more than its expected share of havoc on schedules. The Academy of Motion Picture Arts and Sciences, hoping to broaden its reach among those with strict curfews and short attention spans, opted to kick off the show at the previously unheard-of time of 4 P.M. Or, as this year's host, Jimmy Kimmel, quipped in his opening monologue, "The show, as you know, is starting an hour early this year, but don't worry. It will still end very, very late." Such temporal dislocation was surely a good omen, not that any were needed, for Christopher Nolan and "Oppenheimer."


Christopher Nolan on the Promise and Peril of Technology

The Atlantic - Technology

By the time I sat down with Christopher Nolan in his posh hotel suite not far from the White House, I guessed that he was tired of Washington, D.C. The day before, he'd toured the Oval Office and had lunch on Capitol Hill. Later that night, I'd watched him receive an award from the Federation for American Scientists, an organization that counts Robert Oppenheimer, the subject of Nolan's most recent film, among its founders. He'd endured a joke, repeated too many times by Senate Majority Leader Chuck Schumer, about the subject of his next film--"It's another biopic: Schumer." The award was sitting on an end table next to Nolan, who was dressed in brown slacks, a gray vest, and a navy suit jacket--his Anglo-formality undimmed by decades spent living in Los Angeles. "It's heavy, and glass, and good for self-defense," he said of the award, while filling his teacup.


Christopher Nolan says AI experts face their 'Oppenheimer moment'

The Guardian

The Oppenheimer director, Christopher Nolan, has highlighted the difficulties of applying nuclear weapons-style regulation to artificial intelligence, as he warned that the United Nations had become a "very diminished" force. Nolan told the Guardian J Robert Oppenheimer's call for international control of nuclear weapons had "sort of come true", but there had nonetheless been extensive proliferation of the technology since the "father of the atomic bomb" led the Manhattan project in the second world war. "To look at the international control of nuclear weapons and feel that the same principles could be applied to something that doesn't require massive industrial processes – it's a bit tricky," he said. "International surveillance of nuclear weapons is possible because nuclear weapons are very difficult to build. Oppenheimer spent $2bn and used thousands of people across America to build those first bombs. It's reassuringly difficult to make nuclear weapons and so it's relatively easy to spot when a country is doing that. I don't believe any of that applies to AI."

More than 1,300 experts call AI a force for good

BBC News

That letter suggested super-intelligent AI posed an "existential risk" to humanity. This was a view echoed by film director Christopher Nolan, who told the BBC that AI leaders he spoke to saw the present time "as their Oppenheimer moment". J.Robert Oppenheimer played a key role in the development of the first atomic bomb, and is the subject of Mr Nolan's latest film.
