Adaptive versus non-adaptive sampling for Gaussian-RBF surrogates: a replicated benchmark across analytical and differential-equation models

A controlled, replicated comparison of nine sampling strategies within a fixed Gaussian radial-basis-function (RBF) pipeline and examines when sequential acquisition is justified, finding geometry-retaining adaptive criteria improve Heat, Graetz and both four-parameter 2S-RD QoIs, whereas LHS remains effective on both two-parameter QoIs.
