A mixed integer nonlinear programming formulation for the problem of fitting positive exponential sums to empirical data [PDF]
Opuscula Mathematica, 2011 In this work we deal with exponential sum models coming from data acquisition in the empirical sciences. We present a two step approach based on Tikhonov regularization and combinatorial optimization, to obtain stable parameter estimations, which fit the

Exact Optimal Designs of Experiments for Factorial Models via Mixed-Integer Semidefinite Programming
Mathematics, 2023 The systematic design of exact optimal designs of experiments is typically challenging, as it results in nonconvex optimization problems. The literature on the computation of model-based exact optimal designs of experiments via mathematical programming ...

Transformation of propositional calculus statements into integer and mixed integer programs: An approach towards automatic reformulation [PDF]
, 1990 A systematic procedure for transforming a set of logical statements or logical conditions imposed on a model into an Integer Linear Progamming (ILP) formulation Mixed Integer Programming (MIP) formulation is presented. An ILP stated as a system of linear

Optimal Configuration of Gas Solid Separation Equipment Using Mixed Integer Nonlinear Programming
Atmosphere, 2022 The separation of solid particles from gas-solid process streams is an important unit operation in many chemical processes. Out of the many different types of separation equipment that are used for gas-solid separation, cyclone separators are widely used

Undecidability and hardness in mixed-integer nonlinear programming [PDF]
RAIRO - Operations Research, 2019 We survey two aspects of mixed-integer nonlinear programming which have attracted less attention (so far) than solution methods, solvers and applications: namely, whether the class of these problems can be solved algorithmically, and, for the subclasses which can, whether they are hard to solve.

Revisiting lagrange relaxation (LR) for processing large-scale mixed integer programming (MIP) problems [PDF]
, 2004 Lagrangean Relaxation has been successfully applied to process many well known instances of NP-hard Mixed Integer Programming problems. In this paper we present a Lagrangean Relaxation based generic solver for processing Mixed Integer Programming ...
