Typically, non-deterministic models of spatial or time dependent uncertainty are modelled
using the well-established random field framework. However, while tailored for exactly these …

While, In General, Uncertainty Quantification (UQ) Is NP-Hard, Many Practical UQ Problems Can Be Made Feasible

A Gray, S Ferson, O Kosheleva… - 2021 IEEE Symposium …, 2021 - ieeexplore.ieee.org
In general, many general mathematical formulations of uncertainty quantification problems
are NP-hard, meaning that (unless it turned out that P= NP) no feasible algorithm is possible …
