Dispatching vehicle fleets to serve flights is a key task in airport ground handling (AGH). Due to the notable growth of flights, it is challenging to simultaneously schedule multiple types of operations (services) for a large number of flights, where each type of operation is performed by one specific vehicle fleet. To tackle this issue, we first represent the operation scheduling as a complex vehicle routing problem and formulate it as a mixed integer linear programming (MILP) model. Then given the graph representation of the MILP model, we propose a learning assisted large neighborhood search (LNS) method using data generated based on real scenarios, where we integrate imitation learning and graph convolutional network (GCN) to learn a destroy operator to automatically select variables, and employ an off-the-shelf solver as the repair operator to reoptimize the selected variables. Experimental results based on a real airport show that the proposed method allows for handling up to 200 flights with 10 types of operations simultaneously, and outperforms state-of-the-art methods. Moreover, the learned method performs consistently accompanying different solvers, and generalizes well on larger instances, verifying the versatility and scalability of our method.

We introduce LLaMA, a collection of foundation language models ranging from 7B to 65B parameters. We train our models on trillions of tokens, and show that it is possible to train state-of-the-art models using publicly available datasets exclusively, without resorting to proprietary and inaccessible datasets. In particular, LLaMA-13B outperforms GPT-3 (175B) on most benchmarks, and LLaMA-65B is competitive with the best models, Chinchilla-70B and PaLM-540B. We release all our models to the research community.

In a fair world, technology should be accessible to all and used for humanity's betterment. However, there is a growing concern that AI could be monopolised for vested interests by large corporations. This is why open sourcing is paramount. ChatGPT, the popular chatbot by OpenAI, has been one of the biggest breakthroughs in AI. In just five days since its launch, approximately one million individuals engaged with the bot and it is expected that the number will soon reach the billion mark.

Indeed, when other Futurism employees asked the AI to write a bio, theirs were similarly littered with incorrect information. The author of this piece, Maggie Harrison, apparently studied "physics and computer science at the Massachusetts Institute of Technology (MIT)," has written "several influential books," and was even named one of Forbes' yearly "30 under 30" winners. But the chatbot's penchant for resume embellishment doesn't just apply to Futurism employees. When Gary N. Smith, an economist and Pomona College professor who recently co-wrote an essay for Salon arguing that generative AI is doomed to be an economic bubble, asked ChatGPT to write a bio for him, the bot only got one thing right: the fact that he was a professor at Pomona College. The rest of the AI-generated bio, however, despite sounding really nice -- according to ChatGPT, Smith has "served as a consultant to the World Bank, the International Monetary Fund, and United Nations Development Program" and has been "awarded numerous honors for his work in economics, including the Founder's Award from the Claremont Graduate University in 2010" -- was, according to Smith, entirely fabricated. The same goes for a growing number of netizens, some of whom have taken to Twitter to lampoon ChatGPT for their made-up life stories.

Kurt "The CyberGuy" Knutsson explains how to save money on gas. What do you think of a fourth traffic light color being added to traffic signals for self-driving vehicles to help control traffic flow? I get that one day a bunch of connected autonomous cars may outnumber human beings behind the wheel. The thing is, it would tick me off to no end if somehow traffic lights allowed driverless cars an advantage over those driven by you and me. CLICK TO GET KURT'S CYBERGUY NEWSLETTER WITH QUICK TIPS, TECH REVIEWS, SECURITY ALERTS AND EASY HOW-TO'S TO MAKE YOU SMARTER A recent study was published by the Institute of Electrical and Electronics Engineers, arguing for exactly that.

Feeld Notes is a column about a middle-aged woman who suddenly realizes she wants to have sex again--and the beguiling app she uses to do it. I know that women aren't supposed to like dick pics. Themselves? (Guys my age never seem to send them.) I'm know I'm supposed to get upset about them. Take them as an affront.

Today I would like to talk about the impact of artificial intelligence on architecture in 2023. Chat gpt completely changed the way of working. Its reputation grew from 0 to 1 million users in just 5 days, which is a differential record for any other platform in the world. In reference to Instagram, it took two months to reach one million users. Lately there has been a lot of boom in architecture and artificial intelligence, in recent years some people think that it is about to transform the world we live in in unimaginable ways and others are a little less optimistic.

Paul Simon is a renowned singer-songwriter with a spectacular career spanning many years. It's no surprise that he is regarded as one of the most important individuals in popular music given his body of work, which features hit singles, honorable mention albums, and countless collaborations. But what precisely about Paul Simon's background makes it so impressive? His songwriting is unrivaled, first and foremost. Paul has penned some of the most enduring and well-loved songs of the 20th century, from his early work with Simon and Garfunkel to his solo career and collaborations with musicians like Graceland.

In the realm of acting, Glenn Close is a force to be reckoned with. She has established herself as one of the most accomplished and adaptable actresses of her generation throughout a career spanning more than four decades. Do you own a copy of "Fatal Attraction"? Close received an Academy Award nomination for Best Actress for her portrayal of a lady with mental instability. You might also enjoy "Dangerous Liaisons," in which she portrayed the crafty and deceitful Marquise de Merteuil, garnering her a second Oscar nomination.

Did you know that David Hasselhoff's CV goes far beyond his duties as the renowned Baywatch star and a judge on America's Got Talent? Hasselhoff has demonstrated repeatedly throughout the course of a career spanning more than five decades that he is a gifted performer with a wide range of skills. He has a successful track record, to begin with. He became well-known in the 1980s thanks to his portrayal of Michael Knight on Knight Rider, and his popularity grew in the 1990s thanks to his work on Baywatch. Hasselhoff has achieved success as a musician in addition to his acting career, with singles including "Looking for Freedom" and "Hooked on a Feeling."
