Recently the problem of groundwater management has been approached by several optimization techniques including the classical linear/nonlinear programming methods, simulated annealing, neural networks, genetic algorithms and the outer approximation method. The ‘outer approximation’ method is a global optimization technique for the minimization of a concave function over a compact set of constraints. The concept of this method, as well as applications of the method to groundwater management, problems, was first presented by the authors for problems with a convex set of constraints (Karatzas and finder, [1993]), and in a later work for a non-convex set of constraints (baratzas and finder, [1991]). |
