Connections between Nonlinear Programming and Discrete Optimization

  • Franco Giannessi
  • Fabio Tardella


Given a set X,a function f: X→ℝ and a subset S of X we consider the problem:
$$\min f(x)s.t.x \in S$$
Problem (1) is usually called a combinatorial optimization problem when S is finite and a discrete optimization problem when the points of S are isolated in some topology, i.e., every point of S has a neighbourhood which does not contain other points of S. Obviously, all combinatorial optimization problems are also discrete optimization problems but the converse is not true. A simple example is the problem of minimizing a function on the set of integer points contained in an unbounded polyhedron.
