A parametric integer programming algorithm for bilevel mixed integer programs [PDF]

, 2009
We consider discrete bilevel optimization problems where the follower solves an integer program with a fixed number of variables. Using recent results in parametric integer programming, we present polynomial time algorithms for pure and mixed integer ...

Optimal STATCOM Allocation Using Mixed Integer Distributed Ant Colony Optimization

2023 IEEE Conference on Power Electronics and Renewable Energy (CPERE), 2023
This paper presents a novel optimization approach to find the optimal STATCOM installation in the power system using Mixed Integer Distributed Ant Colony optimization (MIDACO). The proposed method is mathematically formulated based on minimizing the Voltage Deviation Index (VDI) and the installation cost of STATCOM.

Lifting Linear Extension Complexity Bounds to the Mixed-Integer Setting

, 2017
Mixed-integer mathematical programs are among the most commonly used models for a wide set of problems in Operations Research and related fields. However, there is still very little known about what can be expressed by small mixed-integer programs.

Optimal training of integer-valued neural networks with mixed integer programming

PLOS ONE, 2023
Recent work has shown potential in using Mixed Integer Programming (MIP) solvers to optimize certain aspects of neural networks (NNs). However the intriguing approach of training NNs with MIP solvers is under-explored. State-of-the-art-methods to train NNs are typically gradient-based and require significant data, computation on GPUs, and extensive ...
