Time‑Varying Bayesian Optimization (TVBO) is a framework for optimizing expensive, noisy black‑box functions that change over time. Existing TVBO algorithms assume observations are taken at a constant frequency, an assumption that becomes unrealistic as Gaussian‑process inference scales with the cube of dataset size. This paper relaxes that assumption, derives the first upper regret bound that incorporates variable sampling frequency, and uses the analysis to give practical guidance on dataset sizes and stale‑data policies. An algorithm (BOLT) that follows these recommendations outperforms the current state‑of‑the‑art TVBO methods on both synthetic and real‑world experiments.
