1. From Declarative Models to Local Search
Sammanfattning : A solver is a general-purpose software for solving optimisation problems. It takes as input a description of a problem, called a model, and uses a collection of algorithms, called its solving technology, to ideally produce an optimal solution as output. Most solvers have a modelling language that cannot be processed by other solvers. LÄS MER
2. Graphic Representation and Visualisation as Modelling Support for the Knowledge Acquisition Process
Sammanfattning : The thesis describes steps taken towards using graphic representation and visual modelling support for the knowledge acquisition process in knowledge-based systems – a process commonly regarded as difficult. The performance of the systems depends on the quality of the embedded knowledge, which makes the knowledge acquisition phase particularly significant. LÄS MER
3. Tools for Understanding, Debugging, and Simulation Performance Improvement of Equation-based Models
Sammanfattning : Equation-based object-oriented (EOO) modelling languages provide a convenient, declarative method for describing models of cyber-physical systems.Because of the ease of use of EOO languages, large and complex models can be built with limited effort. LÄS MER
4. Computational Issues in Calculi of Partial Inductive Definitions
Sammanfattning : We study the properties of a number of algorithms proposed to explore the computational space generated by a very simple and general idea: the notion of a mathematical definition and a number of suggested formal interpretations ofthis idea. Theories of partial inductive definitions (PID) constitute a class of logics based on the notion of an inductive definition. LÄS MER
5. Applications and Extensions of Reference Attributed Grammars
Sammanfattning : Programming languages are the main tools used to describe models of the real world and algorithms which manipulate these models. Over time much effort has been devoted to the task of making programming languages more high-level by enhancing their expressiveness, bringing it closer to the way the programmer thinks and reasons.
