The authors present a Lagrangean decomposition to study integer nonlinear programming problems. Solving the dual Lagrangean relaxation they have to obtain at each iteration the solution of a nonlinear programming with continuous variables and an integer linear programming. Decreasing iteratively the primal-dual gap the authors propose two algorithms to treat the integer nonlinear programming.
