The cost of not knowing enough: mixed-integer optimization with implicit Lipschitz nonlinearities

Schmidt, Martin; Sirvent, Mathias; Wollner, Winnifried - In: Optimization Letters 16 (2021) 5, pp. 1355-1372

It is folklore knowledge that nonconvex mixed-integer nonlinear optimization problems can be notoriously hard to solve in practice. In this paper we go one step further and drop analytical properties that are usually taken for granted in mixed-integer nonlinear optimization. First, we only...

The present paper discusses an approach to solve the joint replenishment problem in a production environment with concave production cost functions. Under this environment, the model leads to a global optimization problem, which is investigated by using some standard results from convex...
