The paper provides a practical recipe for implementation, a stability diagnostic, and theoretical justification for its effectiveness. The inclusion of reproducible experiments in constrained language generation and sparse-reward navigation strengthens the claims. The connection to prompted inference is also interesting, suggesting a potential bridge between algorithmic and language-based search strategies. The adaptive control of focusing strength is a key contribution to avoid degeneracy.

    We present a practical framework, \emph{Inverted Causality Focusing Algorithm} (ICFA), that treats search as a target-conditioned reweighting process.
