Trace-Guided Synthesis of Effectful Test Generators

Zhe Zhou, Ankush Desai, Benjamin Delaware +1

Several recently proposed program logics have incorporated notions of underapproximation into their design, enabling them to reason about reachability rather than safety. In this p…

SWE-Hub: A Unified Production System for Scalable, Executable Software Engineering Tasks

Yucheng Zeng, Shupeng Li, Daxiang Dong +11

Progress in software-engineering agents is increasingly constrained by the scarcity of executable, scalable, and realistic data for training and evaluation. This scarcity stems fro…

LOGIGEN: Logic-Driven Generation of Verifiable Agentic Tasks

Yucheng Zeng, Weipeng Lu, Linyun Liu +9

The evolution of Large Language Models (LLMs) from static instruction-followers to autonomous agents necessitates operating within complex, stateful environments to achieve precise…

From Traces to Program Incorrectness: A Type-Theoretic Approach

Yongwei Yuan, Zhe Zhou, Julia Belyakova +2

We present a type-theoretic framework for reasoning about incorrectness in functional programs that interact with effectful, opaque library APIs. Our approach centers on traces --…

Type-Based Incorrectness Reasoning

Zhe Zhou, Benjamin Delaware, Suresh Jagannathan

A coverage type generalizes refinement types found in many functional languages with support for must-style underapproximate reasoning. Property-based testing frameworks are one pa…
