Apple researchers detail P-Complete query evaluation for AI agents

By PulseAugur Editorial · [1 sources] ·

Apple Machine Learning Research has published a paper detailing the P-Completeness of Inverted Index Traversal, addressing the theoretical limits of evaluating complex Boolean queries over inverted indices. The paper introduces a new algorithm called ComputePN, which aims to make query evaluation tractable by decoupling logical negation from universe-scale materialization and utilizing DAG memoization. This approach bounds evaluation time and overcomes the limitations of existing stateful iterator and recursive materialization models, laying a formal foundation for computational retrieval. AI

IMPACT This research could enable more efficient and complex reasoning for AI agents by improving search infrastructure.

    The P-Completeness of Inverted Index Traversal: On the Complexity of Evaluating Boolean Query DAGs

    Modern AI agents increasingly rely on search infrastructure to execute complex, neuro-symbolic reasoning workflows. These workflows often compile into deeply nested, non-monotonic Boolean queries over text fields. However, standard query evaluation strategies over inverted indice…
