2. 1. Constructing Algorithms for Constraint Satisfaction and Related Problems : Methods and Applications

   Author : Ola Angelsmark; Peter Jonsson; Brahim Hnich; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; constraint satisfaction; CSP; graph problems; algorithm construction; computational complexity; microstructures; graph colouring; decision problems; optimisation problems; quantum computing; molecular computing; Computer science; Datavetenskap;

   Abstract : In this thesis, we will discuss the construction of algorithms for solving Constraint Satisfaction Problems (CSPs), and describe two new ways of approaching them. Both approaches are based on the idea that it is sometimes faster to solve a large number of restricted problems than a single, large, problem. READ MORE

4. 2. Interactive Optimisation in Marine Propeller Design

   Author : Ioli Gypa; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; marine propeller design; support-vector machines; machine learning; NSGA-II; optimisation; interactive genetic algorithms; progressively interactive evolutionary computation;

   Abstract : Marine propeller design is a complex engineering problem that depends on the collaboration of several scientific disciplines. During the design process, the blade designers need to consider contradicting requirements and come up with one optimal propeller design as a solution to the specific problem. READ MORE

5. 3. Optimisation methods for solving a large-scale avionics scheduling problem

   Author : Emil Karlsson; Elina Rönnberg; Kaj Holmberg; Simin Nadjm-Tehrani; Musliu Nysret; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Optimisation; Decomposition; Large-scale scheduling; Avionics scheduling;

   Abstract : Modern computer systems in aircraft are based on an integrated modular avionic architecture. In this architecture, software applications share hardware resources on a common avionic platform. Many functions in an aircraft are controlled by software and a failure in such software can have severe consequences. READ MORE

6. 4. A multi-objective evolutionary approach to simulation-based optimisation of real-world problems

   Author : Anna Syberfeldt; Philip Moore; Robert I. John; Amos Ng; Högskolan i Skövde; []
   Keywords : Evolutionary algorithms; simulation-based optimisation; multi-objective optimisation; noise; TECHNOLOGY; TEKNIKVETENSKAP; Teknik; Technology;

   Abstract : This thesis presents a novel evolutionary optimisation algorithm that can improve the quality of solutions in simulation-based optimisation.Simulation-based optimisation is the process of finding optimal parameter settings without explicitly examining each possible configuration of settings.

7. 5. Multiobjective Optimisation and Active Control of Bogie Suspension

   Author : Milad Mousavi Bideleh Seyed; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; global sensitivity analysis; Bogie; active control.; robustness analysis; suspension system; multiobjective optimisation;

   Abstract : Railways provide fast, safe, clean, and cheap transportation service. The cost efficiency inrailway operations can be scrutinized from different perspectives. READ MORE
