  2. 1. Enhancing Differential Evolution Algorithm for Solving Continuous Optimization Problems

    Author : Miguel Leon; Ning Xiong; Yigen Zenlander; Peter Funk; Ronnie Johansson; Mälardalens högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer Science; datavetenskap;

    Abstract : Differential Evolution (DE) has become one of the most important metaheuristics during the recent years, obtaining attractive results in solving many engineering optimization problems. However, the performance of DE is not always strong when seeking optimal solutions. It has two major problems in real world applications. READ MORE

  4. 2. IMPROVING DIFFERENTIAL EVOLUTION WITH ADAPTIVE AND LOCAL SEARCH METHODS

    Author : Miguel Leon; Ning Xiong; Peter Funk; Yigen Zenlander; Kristian Sandström; Mälardalens högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Differential Evolution; Adaptation; Memetic algorithm; Evolutionary Algorithm; Computer Science; datavetenskap;

    Abstract : Differential Evolution (DE) is a population-based algorithm that belongs to the Evolutionary algorithm family. During recent years, DE has become a popular algorithm in optimization due to its strength solving different types of optimization problems and due to its easy usage and implementation. READ MORE

  5. 3. Efficient crystal plasticity simulations of microstructure evolution

    Author : Ylva Mellbin; Hållfasthetslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : One of the common tools for studying the deformation behavior of the microstructure in polycrystalline materials is crystal plasticity models. These are used to describe texture evolution and hardening due to crystallographic slip. READ MORE

  7. 5. Homogenization of some linear and nonlinear partial differential equations

    Author : Niklas Wellander; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Matematik;

    Abstract : In this thesis is studied two-scale convergence for sequences of linear and nonlinear evolution problems. In particular homogenization procedures, correctors and a numerical algorithm for such problems are studied. The main results are the following: We prove a crucial compactness results of two-scale convergence type. READ MORE
