摘要

Even when reduced-order bases can be determined for a given problem, the just seen procedures work by projection of the problem onto the subspace spanned by these bases (standard POD formulation, already described in Sect. 23 ). This makes it difficult to obtain results under severe real-time feedback constraints. In that case surrogates are often preferred.
