  • Multi-objective optimization of vehicle routing problem using evolutionary algorithm with memory 

    Wiatrowski, Grzegorz ORCID; Podlaski, Krzysztof ORCID (AGH Publishing House, 2017)
    The idea of a new evolutionary algorithm with memory aspect included is proposed to find multiobjective optimized solution of vehicle routing problem with time windows. This algorithm uses population of agents that ...
  • Absorption effects in the blazar’s γ-ray spectra due to luminous stars crossing the jet 

    Sitarek, Julian ORCID; Bednarek, Włodzimierz ORCID (Royal Astronomical Society, 2021)
    γ-ray emission in active galaxies is likely produced within the inner jet, or in the close vicinity of the supermassive black hole (SMBH) at sub-parsec distances. γ-rays have to pass through the surrounding massive stellar ...
