Imputing a convex objective function
Witryna12 paź 2024 · An objective function may have a single best solution, referred to as the global optimum of the objective function. Alternatively, the objective function may have many global optima, in which case we may be interested in locating one or all of them. ... Convex Optimization, 2004. Numerical Optimization, 2006. Articles. … Witryna1 maj 2024 · Given an observation as input, the inverse optimization problem determines objective function parameters of an (forward) optimization problem that make the observation an (often approximately) optimal solution for the forward problem.

Imputing a convex objective function. Abstract: We consider an optimizing process (or parametric optimization problem), i.e., an optimization problem that depends on some parameters. We present a method for imputing or estimating the objective function, based on observations of optimal or nearly optimal choices of the variable for several ... Witryna21 cze 2016 · 8. I understand that a convex function is a great object function since a local minimum is the global minimum. However, there are non-convex functions that also carry this property. For example, this figure shows a non-convex function that carries the above property. It seems to me that, as long as the local minimum is the …
