The paper introduces FactoSR, a factorized reinforcement learning framework designed to improve spatial reasoning in Vision‑Language Models by addressing a dimensional mismatch between 2D visual inputs and the 3D+temporal nature of the physical world. FactoSR decomposes the reasoning task into three orthogonal geometric sub‑objectives—planar correspondence (XY), depth consistency (Z), and temporal reversibility (T)—and optimizes these constraints within a unified policy learning mechanism. Experiments on multi‑view and video benchmarks show that this decomposition yields significant performance gains, achieving a 5.9% improvement on VSI‑Bench and 4.5% on All‑Angles‑Bench.

CoEvolve is a construct-to-edit framework for visual grounding that separates the task into explicit state construction and state editing. It uses Region‑Evolution Reinforcement to progressively refine candidate regions and Bidirectional Denoising Refiner to adjust coordinate fields based on fixed semantic context. The approach achieves high grounding accuracy with a 9B backbone, rivaling much larger models, and can recover over 27 percentage points in mean box overlap after a single refinement pass.
