Complexity Aspects in Design for Sustainability

Anthropogenic environmental impact is growing despite large technical efforts to reduce it. Its dependency on technology induced human behaviour makes designing for environmental impact reduction particularly difficult. Despite the fact that the sustainable conundrum is characterized as a “no technical solution problem”, a framework is proposed...

A cognitive model for software architecture complexity

Evaluating the complexity of the architecture of a softwaresystem is a difficult task. Many aspects have to be considered to come to a balanced assessment. Several architecture evaluation methods have been proposed, but very few define a quality model to be used during the evaluation process. In addition, those methods that do introduce a...

A Class of Large-Update and Small-Update Primal-Dual Interior-Point Algorithms for Linear Optimization

In this paper we present a class of polynomial primal-dual interior-point algorithms for linear optimization based on a new class of kernel functions. This class is fairly general and includes the classical logarithmic function, the prototype self-regular function, and non-self-regular kernel functions as special cases. The analysis of the...
