Deduction-Guided Reinforcement Learning
Overview
Deduction-Guided Reinforcement Learning is a technique that combines deductive reasoning (logical, constraint-based inference) with reinforcement learning to guide a learning-based search process. It was introduced in the context of synthesizing programs, where deduction provides structural or logical guidance to a reinforcement learning policy that navigates the space of candidate programs.
Origin and Publication
The technique was formalized in the 2020 paper "Program Synthesis Using Deduction-Guided Reinforcement Learning" by Yanju Chen, Chenglong Wang, Osbert Bastani, Işıl Dillig, and Yu Feng. The work appeared in the Lecture Notes in Computer Science series (pages 587–610) and was assigned the DOI 10.1007/978-3-030-53291-8_30.
Application: Program Synthesis
As evidenced by the paper's title and the related-entity mapping, the principal application domain of Deduction-Guided Reinforcement Learning is Program Synthesis — the task of automatically generating programs from high-level specifications (such as input/output examples, logical constraints, or natural-language intent). In this setting, deductive reasoning is used to prune, constrain, or guide the search, while reinforcement learning provides a learned policy for selecting program construction actions.
Relation to Other Synthesis Approaches
The technique sits at the intersection of:
- Deductive / constraint-based synthesis, which uses logical reasoning (e.g., SMT solvers, conflict-driven learning) to prune the program space.
- Learning-based synthesis, which uses statistical learning — including reinforcement learning — to bias program construction.
Earlier and contemporaneous program-synthesis research that the technique can be compared against includes conflict-driven learning approaches (Feng et al., 2018), Datalog synthesis via numerical relaxation (Si et al., 2019), and frameworks that synthesize the most probable program under a specification (Xiong & Wang, 2022). All of these works are catalogued alongside the originating paper in the Genesys reference set.
Evidence Summary
The only direct bibliographic evidence for this technique is a single LNCS citation listing. As such, this article is intentionally conservative and confines its claims to what that citation, together with the provided related-entity mapping, explicitly supports.
