Abstract:
Rigorous convex underestimators for a broad class of variational and optimal control problems are developed. These rely only on the functional form of a nonconvex variational or optimal control problem, and therefore are quite general. The notion of convex underestimators is used extensively in modern algorithms for the global optimization of nonconvex algebraic problems (NLP, INLP and MINLP). However, the application of variational convex underestimators to global optimization algorithms for variational problems does not proceed directly by analogy. Progress towards this goal will be reported.
