Witryna1 sie 2006 · Abstract and Figures. This paper studies subspace properties of trust region methods for unconstrained optimization, assuming the approximate Hessian is updated by quasi- Newton formulae and the ... WitrynaSummary The goal of field-development optimization is maximizing the expected value of an objective function, e.g., net present value for a producing oil field or amount of CO2 stored in a subsurface formation, over an ensemble of models that describe the uncertainty range. A single evaluation of the objective function requires solving a …
