OPTIMA Mathematical Optimization Society Newsletter 89

August 1, 2012. While preparing this column and in my periodic and frantic search for material of interest, I stumbled on this most appropriate motto: Optimum is maximum at a minimum – due to the nu-jazz artist Mr Gaus (no, this is not made up). In view of the coming ISMP festivi

Comments on: Farkas’ lemma: three decades of generalizations for mathematical optimization

The celebrated Farkas lemma originated in Farkas (1902) provides us an attractively simple and extremely useful characterization for a linear inequality to be a consequence of a linear inequality system on the Euclidean space Rn . This lemma has been extensively studied and exten

CUTEst: a Constrained and Unconstrained Testing Environment with safe threads for mathematical optimization

Wedescribe themost recent evolution of our constrained and unconstrained testing environment and its accompanying SIF decoder. Code-named SIFDecode and CUTEst, these updated versions feature dynamic memory allocation, a modern thread-safe Fortran modular design, a new Matlab inte

Mathematical Optimization of the Combination of Radiation and Differentiation Therapies for Cancer

Cancer stem cells (CSC) are considered to be a major driver of cancer progression and successful therapies must control CSCs. However, CSC are often less sensitive to treatment and they might survive radiation and/or chemotherapies. In this paper we combine radiation treatment wi

Large-Scale Transit Network Optimization

This article proposes a methodology for developing optimal transit networks (route structures and headways) that minimizes transit transfers and total user cost while maximizing service coverage, given information on transit demand, transit fleet size, and the street network of t

Review of optimization models for integrated process water networks and their application to biofuel processes

This paper provides an overview of recent development in the area of optimal synthesis of process water networks in which a major goal is to reduce the freshwater consumption by the reuse and recycle of process and treatment streams. The recent models can globally optimize these

Advanced Modeling and Optimization for Virtual Calibration of Internal Combustion Engines

Due to the high complexity of modern internal combustion engines and powertrain systems, the proper calibration of the electronic control unit’s (ECU) parameters has a strong impact on project targets like fuel consumption, emissions and drivability, as well as development costs

Prediction of optimal operating parameters for continuous casting of billets

Process optimization determines process parameters that maximize or minimize (optimize) so aspect of a process (the obieciive function), while ensuring that the process operates wr established limits. In this work a mathematical model that simulates heat flow and solidification c
