However, RL policies are not always trained with ethical behavior in mind, which can lead an agent to violate social or legal norms in pursuit of its goal. Retraining agents with additional norms is not always feasible, especially in complex stochastic environments. To mitigate this issue, we present a probabilistic policy fixing framework that adapts norm-agnostic policies online. Using Answer Set Programming (ASP), we generate policy fixes that minimize deviations from the RL policy while optimizing for norm adherence against a set of sampled worlds. Based on the Rule of Three and Hoeffding's inequality, we provide guarantees that fixed policies are near optimal, given a specified level of confidence.","doi":"10.24963/ijcai.2026/419","url":"https://ijcai.org/proceedings/2026/419","pdf":"https://ijcai.org/proceedings/2026/0419.pdf","markdown":"https://ijcai.org/proceedings/2026/419.md","bibtex":"https://ijcai.org/proceedings/2026/bibtex/419","volume":{"slug":"2026","title":"Proceedings of the Thirty-Fifth International Joint Conference on Artificial Intelligence","short_title":"IJCAI 2026","url":"https://ijcai.org/proceedings/2026/","year":2026,"location":"Bremen, Germany","dates":"15-21 August 2026","editors":"Diego Calvanese","isbn":"978-1-956792-09-6","publisher":"International Joint Conferences on Artificial Intelligence Organization","doi_prefix":"10.24963/ijcai.2026"},"section":"Knowledge Representation and Reasoning","track":"Main Track","number":419,"pages":{"first":3765,"last":3773},"keywords":["Knowledge Representation and Reasoning: Reasoning about actions","Knowledge Representation and Reasoning: Logic programming"],"videos":[],"references":[],"license_note":"Copyright International Joint Conferences on Artificial Intelligence."}
