Abstract :
We describe a generalization of the level method for solving a nondifferentiable program where the problem data (feasible set, functionvalues, and subgradients) are not known explicitely and may be approximated using an oracle only up to an appropriately chosen accuracy. We show that it produces an approximately feasible and optimal solution after a finite number of oracle calls.
