Convexification of Multi-period Quadratic Programs with Indicators
Jisun Lee, Andrés Gómez, Alper Atamtürk
We study a multi-period convex quadratic optimization problem, where the state evolves dynamically as an affine function of the state, control, and indicator variables in each peri…
Strong Formulations for Hybrid System Control
Jisun Lee, Hyungki Im, Alper Atamtürk
We study the mixed-integer quadratic programming formulation of an -period hybrid control problem with a convex quadratic cost function and linear dynamics. We first give the co…
Safe Screening Rules for -Regression
Alper Atamtürk, Andrés Gómez
We give safe screening rules to eliminate variables from regression with regularization or cardinality constraint. These rules are based on guarantees that a feature may o…
Accommodating new flights into an existing airline flight schedule
Ozge Safak, Alper Atamturk, Selim M. Akturk
We present two novel approaches to alter a flight network for introducing new flights while maximizing airline's profit. A key feature of the first approach is to adjust the aircra…
Strong Formulations for Quadratic Optimization with M-matrices and Indicator Variables
Alper Atamturk, Andres Gomez
We study quadratic optimization with indicator variables and an M-matrix, i.e., a PSD matrix with non-positive off-diagonal entries, which arises directly in image segmentation and…
