#Workshop Call for Contributions #CfP: The Fourth Workshop on Computational Fair Division. ⏰ Submission deadline: 9 May, 2026 πŸ“Œhttps://sites.google.com/view/fairdivisionworkshop2026/call-for-contributions?authuser=0 #IJCAI2026 #ECAI2026 #AI

There's only one solution: reject due to academic misconduct. It's not about correctness of findings or proofs, as scholars we need to be educators as well. A good paper is not just about it's results, it's equally about providing educational value.

Apparently the NeurIPS chairs decided to reopen the camera-ready submission to ensure "that the proceedings reflect the highest scientific quality.” @neuripsconf.bsky.social, is that true? So the solution to academic misconduct is to give the authors a chance to cover their tracks?

I am recruiting PhD students at NYU Courant to conduct research in learning theory, algorithmic statistics, and trustworthy machine learning, starting Fall 2026. Please share widely! Deadline to apply is December 12, 2025.

Verdict: Even top-tier reasoning models struggle when: - generating stable solutions, - detecting blocking pairs (instabilities), - repairing unstable matchings, or - scaling reasoning to larger markets.

2️⃣ Algorithmic, step-by-step reasoning. In computer science education, we call this algorithmic thinking, i.e. the capacity to follow and adapt structured procedures. It’s what allows us to detect errors, repair them, and maintain logical consistency.

Why matching markets? 1. They require reasoning over ranked preferences (who prefers whom) while following iterative algorithms. They’re the ideal stress test for LLM reasoning. 2. They’re everywhere: assigning students to schools, workers to jobs, riders to drivers, and even content to users.

πŸ€– Two abilities are essential: 1️⃣ Understanding and reasoning about preferences. They must grasp which option is more desirable: Is a 9 AM meeting better than 7 AM? Is candidate A preferred to B? This is about comprehending relative value and priority, not just data.

3️⃣ Selection from a menu aligns better than generation. When asked to select from a preselected menu of options, some models (GPT-4o and Claude-3.5) display more human-like fairness, prioritizing equitability.

1️⃣ LLMs are often misaligned with human notions of fairness. They seldom minimize inequality (equitability), instead favoring envy-freeness or efficiency. 2️⃣ When money is available, humans use it to restore balance, equalizing utilities; most LLMs do not.

Are you at @iclr-conf.bsky.social ? Check out our new work on game-theoretic evaluation of language models! Also go say hi πŸ‘‹ and chat with @liusiqi.bsky.social, @drimgemp.bsky.social, and @lukemarris.bsky.social in person! 🀩

Siqi Liu (εˆ˜ζ€ε₯‡)@liusiqi.bsky.social

Frontier models are often compared on crowdsourced user prompts - user prompts can be low-quality, biased and redundant, making "performance on average" hard to trust. Come find us at #ICLR2025 to discuss game-theoretic evaluation (shorturl.at/0QtBj)! See you in Singapore!

Looking for a principled evaluation method for ranking of *general* agents or models, i.e. that get evaluated across a myriad of different tasks? I’m delighted to tell you about our new paper, Soft Condorcet Optimization (SCO) for Ranking of General Agents, to be presented at AAMAS 2025! 🧡 1/N

This is a fantastic idea. We need a similar journal for AI and CS. Benefits: i) ensuring integrity of findings, ii) encouraging scientific method, iii) promoting critical evaluation, iv) solid publications for junior researchers.
