Since Dantzig-Wolfe’s pioneering contribution, the decomposition approach using a pricing mechanism has been developed for a wide class of mathematical programs. For convex programs a linear space of Lagrangean multipliers is enough to define price functions. For general mathematical programs the price functions could be defined by using a subclass of nondecreasing functions. However the space of non-decreasing functions is no longer finite dimensional. In this paper the authors consider a specific nonconvex optimization problem min{
