  • New concept of convergence(R-convergence)of a sequence of measures was applied to characterize global minimizers in functional space as a sequence of approximating solutions in finite-dimensional spaces.A deviation integral approach was used to find such solutions.For a constrained problem,a penalized deviation integral algorithm was proposed to convert it to unconstrained ones.A numerical example on optimal control problem with non convex state constrains was given to show that the algorithm is efficient.
