A new research paper introduces Bounded Path Context (BPC), a method to optimize Large Language Model (LLM) performance in knowledge graph question answering (KGQA). BPC decouples the controller's full path memory from the prompt, exposing only the last K hops. Experiments on WebQSP and CWQ datasets using Qwen3.5-9B-AWQ demonstrated that BPC with K=1 can match or surpass full-path history prompting, achieving higher F1 scores while reducing input tokens. The study suggests that path serialization length should be a tunable parameter rather than a default assumption for LLM-based graph controllers. AI
