Polynomial and Pseudopolynomial Algorithms for Two Classes of Bin Packing Instances
Announce Type: replace Abstract: The Cutting Stock Problem (CSP) and Bin Packing Problem (BPP) are classical combinatorial optimization problems extensively studied since the 1960s. State-of-the-art exact algorithms are based on set-cover and arc-flow models whose linear relaxation, rounded up, matches the integer optimum for most benchmark instances, a condition known as the Integer Round-up Property (IRUP). In 2016, Delorme et al. showed that all existing instances could be solved within...
ASAP: Exploiting the Satisficing Generalization Edge in Neural Combinatorial Optimization
Announce Type: replace Abstract: Deep Reinforcement Learning (DRL) has emerged as a promising approach for solving Combinatorial Optimization (CO) problems, such as the 3D Bin Packing Problem (3D-BPP), Traveling Salesman Problem (TSP), or Vehicle Routing Problem (VRP), but these neural solvers often exhibit brittleness when facing distribution shifts. To address this issue, we uncover the Satisficing Generalization Edge, which we validate both theoretically and experimentally: identifying a...

22 World Cup items, 22 stories
FIFA won't reveal how, but after every game at the 2026 World Cup this summer, it will be collecting items that will one day document the tournament. It already has the net from the 2018 World Cup final, for example, as well as the tracksuit that Pelé wore at his first World Cup in 1958. The items live in FIFA's various museums, ranging from Vancouver and Miami to Zurich and Hong Kong.
Ahoy, DECmate II the little PDP-8 that could
Now, that's a lot of word processing. But under the hood it's still at least PDP-8 adjacent, even considering its oddities and incompatibilities, and you can make it do many of the things a full-size Eight can. We'll take this basic unit, convert the floppy drives to solid state, tap the video output, and put it through its paces.

Rising pop culture star Rachel Pizzolato concludes massive May at Miami Swim Week, Ric Flair's health & MEAT
The sun is shining bright, Monday Screencaps is dialed in, the birds are chirping away, summer is in the air, a skunk unloaded in the early morning hours (thankfully not on my dogs) and it's officially June 2026. Guys, let's face it, this is going to be a massive month for the United States and the world. We have the World Cup, America 250, Trump's birthday UFC event, there's an intriguing NBA Finals (if you're into that sort of thing), the NHL Finals are ready to roll and there's even that...
CT scans of BYD car parts
Design to Reality Evolution of the Plastic Bottle In the dark nights of my soul, I fret about how inconsistently engineered my life is. The coffee table I made a year or two ago was intended to look like the dining room table I built a few years earlier, but in reality the two bear only a vague resemblance to each other. Open a drawer of my tool chest at random, and perhaps you’ll find a thematically-aligned collection of well-loved hand tools, meticulously cut into a nest of Kaizen foam, or...
