A mixed integer nonlinear programming formulation for the problem of fitting positive exponential sums to empirical data [PDF]

open access: yesOpuscula 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

open access: yesMathematics, 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 ...

Optimal Operation of Soft Open Points-Based Energy Storage in Active Distribution Networks by Considering the Battery Lifetime

open access: yesFrontiers in Energy Research, 2021
Soft open point-based energy storage (SOP-based ES) can transfer power in time and space and also regulate reactive power. These characteristics help promote the integration of distributed generations (DGs) and reduce the operating cost of active ...

Undecidability and hardness in mixed-integer nonlinear programming [PDF]

open access: yesRAIRO - 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.
