On solving large-scale multistage stochastic problems with a new specialized interior-point approach
(2021-12)
Research report
Open AccessA novel approach based on a specialized interior-point method (IPM) is presented for solving large-scale stochastic multistage continuous optimization problems, which represent the uncertainty in strategic multistage and ... -
New interior-point approach for one- and two-class linear support vector machines using multiple variable splitting
(2021-12)
Research report
Open AccessMultiple variable splitting is a general technique for decomposing problems by using copies of variables and additional linking constraints that equate their values. The resulting large optimization problem can be solved ... -
Transport analytics approaches to the dynamic origin-destination estimation problem
(2020-10)
Research report
Restricted access - author's decisionDynamic traffic models require dynamic inputs, and one of the main inputs are the Dynamic Origin-Destinations (OD) matrices describing the variability over time of the trip patterns across the network. The Dynamic OD Matrix ... -
