  Dozorowanie nisz stanowi mechanizm, którego celem jest utrzymanie gorzej przystosowanych osobników tak, aby populacja była różnorodna, zawierała odpowiednią liczbę istniejących gatunków, zarówno tych bardziej licznych, jak i tych mniej licznych, a przez to nie powodowała przedwczesnej zbieżności algorytmów ewolucyjnych. Efekt taki uzyskuje się poprzez odpowiednią modyfikację stopnia przystosowania lub rang osobników (zwiększa się...

• W-dominance: Tradeoff-inspired dominance relation for preference-based evolutionary multi-objective optimization

  Publication

  • R. Szłapczyński
  • J. Szłapczyńska

  - Swarm and Evolutionary Computation - Year 2021

  The paper presents a method of incorporating decision maker preferences into multi-objective meta-heuristics. It is based on tradeoffcoefficients and extends their applicability from bi-objective to multi-objective. The method assumes that a decision maker specifies a priori each objective’s importance as a weight interval. Based on this, w-dominance relation is introduced, which extends Pareto dominance. By replacing reference...

  - Year 2009

  The computer algorithms were used for reconstruction of streamer 3D structure. We propose the 3D tree structure model of corona discharge streamer composed with nodes and edges between chosen couples of nodes, which enables easy computation of some important parameters ofstreamers. The 3D model can be derived directly from two projection images by global methods like evolutionary searching or particle simulations. In this paper...

• Shape Optimisation of Kaplan Turbine Blades Using Genetic Algorithms

  Publication

  • M. Banaszek

  - Year 2017

  This monograph is a comprehensive guide to a method of blade profile optimisation for Kaplan-type turbines. This method is based on modelling the interaction between rotor and stator blades. Additionally, the shape of the draft tube is investigated. The influence of the periodic boundary condition vs. full geometry is also discussed. Evolutionary algorithms (EA) are used as an optimisation method together with artificial neural...

  - Year 2010

  In this paper, the method of reconstruction of the 3D structure of streamers in DC positive corona discharge in nozzle-to-plate electrode configuration is presented. For reconstructing of 3D image of corona discharge streamer we propose a stereographical method, where streamers are observed from several directions simultaneously. The multi-directional observation enabled to obtain fine positional coordinates of streamers for a...

  • B. Jaworski
  • R. Śmierzchalski

  - LECTURE NOTES IN COMPUTER SCIENCE - Year 2011

  This article compares an impact of using various selection schemes on the quality of the solution for the problem of planning the path for a moving object using the evolutionary method. In study case problem of avoiding collisions at sea is analyzed. The modelled environment includes static constraints (lands, canals, etc.) and dynamic objects (moving ships). Article analyses behaviour of selection schemes in two similar environments...

• Impact of Initial Population on Evolutionary Path Planning Algorithm

  Publication

  • Ł. Kuczkowski
  • R. Śmierzchalski

  - Year 2014

  In this paper an impact of initial population on evolutionary path planning algorithm is presented. Tested algorithm is used to determine close to optimal ship paths in collision avoidance situation. For this purpose a path planning problem is defined. A specific structure of the individual path and fitness function is presented. For the simulation purposes a close to real tested environment is created. Four tests are performed....
