Sampling-based least squares regression is used to project the system response onto a set of orthogonal bases, providing a representation of the ΔV required for rendezvous as a reduced-order surrogate model.
In recent years, our research group has formulated a new framework called materials knowledge systems (MKS) for establishing highly accurate reduced-order (surrogate) models for localization (opposite of homogenization) linkages in hierarchical materials systems.
A first order Markov surrogate is a symbol sequence constructed by a constrained randomization that has the same length and same [PIJ] as the original symbol sequence.
CORIG is determined, surrogates are constructed (in this case first order Markov surrogates), and values of CSurrogate are calculated.

This study will develop a new high-order polynomial surrogate model (HOPSM) to overcome routines of expensive computer simulations in engineering.
This result indicates the absence of predictive structures beyond the first symbol iteration, which is consistent with the results obtained with first order Markov surrogates in a later section of this paper.
We thus investigate several methods of down-sampling the co-presence signal in order to create surrogate contact networks, in the spirit of [28, 29], and compare these surrogate data to the actual networks of face-to-face contacts.
A computational methodology is proposed for CFD-based aerodynamic design to exploit a reduced order model as surrogate evaluator.
The proposed algorithm is then used to construct a reduced order model (a surrogate) which is then used in a Bayesian approach to calibrate the neutronics and thermal-hydraulics parameters.
