Graphical models with higher order factors are an important tool for pattern recognition that has recently attracted considerable attention. Inference based on such models is challenging both from the view point of software design and optimization theory. In this article, we use the new C++ template library OpenGM to empirically compare inference algorithms on a set of synthetic and real-world ...

This paper presents an interactive graphical user interface (GUI) based multiobjective evolutionary algorithm (MOEA) toolbox for effective computer-aided multiobjective (MO) optimization. Without the need of aggregating multiple criteria into a compromise function, it incorporates the concept of Pareto's optimality to evolve a family of nondominated solutions distributing along the tradeoffs un...

An interactive intuitive graphical simulation package for the analysis of electric distribution systems is presented. It incorporates interactive graphical design of the electric network with a relational data base. The interaction is facilitated with the use of GUI (Graphical User Interface). Two analysis algorithms are integrated allowing the study of load flow conditions as well as the optim...

AnalogExplorer is a computational methodology for the extraction and organization of series of structural analogs from compound data sets and their graphical analysis. The method is suitable for the analysis of large analog series originating from lead optimization programs. Herein we report AnalogExplorer2 designed to explicitly take stereochemical information during graphical analysis into ac...

We address the problem of predicting the size of the search tree explored by Depth-First Branch and Bound (DFBnB) while solving optimization problems over graphical models. Building upon methodology introduced by Knuth and his student Chen, this paper presents a memory-efficient scheme called Retentive Stratified Sampling (RSS). Through empirical evaluation on probabilistic graphical models fro...

Direct manipulation has become the preferred interface for controlling graphical objects. Despite its success, the ad hoc manner with which such interfaces have been designed and implemented restricts the types of interactive controls. This dissertation presents a new approach that provides a systematic method for implementing flexible, combinable interactive controls. This differential approac...

Treatment planning is a trial and error process that determines optimal dwell times, dose distribution, and loading pattern for high dose rate brachytherapy. Planning systems offer a number of dose calculation methods to either normalize or optimize the radiation dose. Each method has its own characteristics for achieving therapeutic dose to mitigate cancer growth without harming contiguous nor...

Abstract The paper utilizes Hölder graphical derivatives for characterizing strong subregularity, isolated calmness and sharp minimum. As applications, we characterize in linear semi-infinite optimization minimizers of some penalty functions constrained optimization.
