NEMO is an AI system that converts natural language descriptions of optimization problems into executable mathematical code using autonomous coding agents. The approach achieves state-of-the-art results on optimization benchmarks by treating code execution as a first-class constraint, ensuring generated solutions are functional by design rather than relying on specialized language models that often produce broken code.
Researchers introduce FEM-Bench, a scientific reasoning benchmark designed to evaluate large language models' ability to generate correct finite element method (FEM) code for computational mechanics problems. Despite the simplicity of introductory-level tasks, current state-of-the-art LLMs show inconsistent performance, with Gemini 3 Pro completing 30/33 tasks at least once and GPT-5 achieving 73.8% success on unit test writing.
Developers increasingly rely on AI tools to write code faster, but research suggests this productivity gain comes at the cost of code quality. The trend poses long-term risks for software reliability and maintenance, potentially creating technical debt that could undermine the benefits of rapid development.

The approach achieves over 80% correctness rates on preference-based reasoning tasks, substantially outperforming traditional LLM baselines that rarely produce feasible solutions.
Researchers introduce RePoT (Recoverable Program-of-Thought), an enhanced AI reasoning method that fixes failed code generation by replaying execution to identify the first error point, then using a single LLM call to recover rather than restarting. The technique improves accuracy by 3-11 percentage points across multiple models and benchmarks, with particularly strong gains on smaller models like GPT-4 mini.
Researchers propose projectional decoding, a framework that integrates semantic validation directly into LLM generation by maintaining a partial graph model alongside text output.

Researchers introduce KLineage, a system that teaches LLM-based agents when to apply GPU kernel optimizations by learning from expert implementations through backward validation rather than forward trial-and-error.
