Postdoctoral Researcher in Logical Reasoning and Machine Learning (ARC Challenge)

The logic and learning (LOL) group is recruiting a postdoc partly funded by the ARC Prize Foundation . You will work with Associate Professor Andrew Cropper . We work on combining logical reasoning and machine learning. We focus on inductive logic programming  (ILP), a form of inductive program synthesis which learns logical rules from data.

The focus of this position is to develop ILP/program synthesis methods for the Abstraction and Reasoning Corpus (ARC) challenge . ARC is a benchmark designed to measure an AI system's ability to efficiently acquire new skills outside its training data. The focus is specifically on ARC-AGI-3 , where systems must learn rules by interacting with their environment.

The research will build on our IJCAI 2025 paper , where we showed that an off-the-shelf ILP system using raw pixels, only arithmetic, and a single CPU could perform reasonably well on ARC-1. 

A start date before September 2026 is ideal but is flexible. The application deadline is February 5, 2026 (at 23:59 UTC +2).

Requirements

• A PhD in computer science or a related topic
• Prior experience in SAT/ASP/SMT/MaxSAT is essential
• Any experience in model counting and a broader understanding of machine learning is also highly desirable
• Excellent English skills
