Using interior point solvers for optimizing progressive lens models with spherical coordinates

Casanellas Peñalver, Glòria; Castro Pérez, Jordi (2019-05)
External research report
Open Access
Designing progressive lenses is a complex problem that has beenpreviously solved by formulating an optimization model based on Cartesiancoordinates. In this work a new progressive lens model using spherical co-ordinates ...
An assigment free data driven approach to the dynamic origin destination matrix estimation problem

Ros Roca, Xavier; Barceló Bugeda, Jaime; Montero Mercadé, Lídia (2020-02-05)
External research report
Open Access
Dynamic 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 ...
