Abstract
- It was earlier demonstrated, by the so-called main (or simplest) problem of the Calculus of Variations, that the Theory of Exact Penalties allows one not only to derive fundamental results of the Calculus of Variations but also to construct new direct numerical methods for solving variational problems based on the notions of subgradient and hypogradient of the exact penalty function (which is essentially nonsmooth even if all initial data are smooth). In this article Exact Penalties are used to solve isoperimetric problems of the Calculus of Variations. New direct numerical methods are described (e.g. the method of hypodifferential descent). Several numerical examples are discussed.
