A dialectical based model coherent with inventive and optimization problems

In an array of problem solving methods, one can traditionally distinguish two kinds of problems: one is a problem that has solutions in a search space and the other is a problem that does not have solutions in a given space. The later problem so called solutionless problem or inventive problem requires an inventive approach to reformulate the problem and dialectical thinking brings benefits in the process. The framework used to formulate problems in a dialectical approach is contradiction. Identification of contradictions plays an important role in distinguishing solutionless problems: a contradiction exists when no solution can be found, and a solution exists when no contradiction can be found. In this article, the inadequacy of existing frameworks in satisfying this requirement is demonstrated and a framework that fits this requirement is proposed.     

Dynamic programming and viscosity solutions for the optimal control of quantum spin systems

The purpose of this paper is to describe the application of the notion of viscosity solutions to solve the Hamilton-Jacobi-Bellman (HJB) equation associated with an important class of optimal control problems for quantum spin systems. The HJB equation that arises in the control problems of interest is a first-order nonlinear partial differential equation defined on a Lie group. Hence we employ recent extensions of the theory of viscosity solutions to Riemannian manifolds in order to interpret possibly non-differentiable solutions to this equation. Results from differential topology on the triangulation of manifolds are then used develop a finite difference approximation method for numerically computing the solution to such problems. The convergence of these approximations is proven using viscosity solution methods. In order to illustrate the techniques developed, these methods are applied to an example problem.     

Decision and stress: cognition and e-accessibility in the information workplace

Cognitive abilities and disabilities are increasingly important in today’s information-based workplace, particularly in relation to the accessibility of advanced information society technologies. As this paper discusses, new technologies can create problems for human decision making, stress levels, general cognition and e-accessibility. Yet it is not easy to identify possible new e-accessibility solutions to these problems. This is where theories of cognitive aspects of e-accessibility could be useful to generate solutions to these problems of HCI in general and of accessibility in particular. The purpose of this paper is to report a new generative theory (called Simplex 2), provide validating evidence for it from two meta-analyses and demonstrate a proof of concept through the application of Simplex to the solution of HCI problems. Two qualitative meta-analyses are reported for two different samples (N ₁ = 90 and N ₂ = 100) of relevant and contemporary conference papers. Whilst a few more concepts were identified, only nine cognitive concepts emerged from both analyses, validating the predictions of Simplex, which is also used for cognitive user modeling. Given the sample sizes and the successful replication, it is clear that these nine factors feature prominently in current research and practice in universal access and inclusive design. Further support for the value of this theory is found in a consideration of the requirements of older adult users and from studies of cognitive overload and augmentation. Uses of Simplex include the evaluation of existing systems, assessment of user requirements, system development in combination with models of task, context of use and technology platform and through the concepts of cognitive augmentation and overload to identify future opportunities for new, accessible, cognitive solutions. A proof of concept of Simplex is demonstrated by the treatment of HCI accessibility problems and as a generative theory for the development of new solutions.     

What is TRIZ? From Conceptual Basics to a Framework for Research

This paper introduces six aspects of the theory of inventive problem solving (TRIZ), from conceptual basics to a framework for interdisciplinary research, and explains some of the specific terminology, such as inventive principles, standard solutions, substance‐field‐systems or contradictions. The conceptual approach of TRIZ comprises the way from a concrete problem over an abstract problem to an abstract solution and from there to a concrete solution. This is supported by a toolkit, which helps the problem‐solver analysing and solving problems in different perspectives. The ‘power supply for notebook computers’ example demonstrates a problem‐solving process with TRIZ using contradiction thinking, the contradiction matrix and the inventive principles as tools. The TRIZ tools may be combined within a comprehensive process model such as ARIS or WOIS, which are briefly discussed. A framework for further research suggests five fields: the tools and their combination as the core, inspiration by new knowledge domains, adaptation to new fields of usage, psycho‐ and sociological contingency and integration with other creativity tools. The paper concludes with an overview of cornerstones in the history of TRIZ and suggests some introductory books and informative websites.
