  Paper presents the application of evolutionary algorithms and polynomial interpolation in ship evolutionary trajectory planning method and its comparison to classic approach, where trajectory is modeled by straight lines. Evolutionary algorithms are group of methods that allows\ to find a collision free trajectory in real time, while polynomial interpolation allows to model smooth trajectory, which keeps continuity of velocity...

  Paper presents the application of evolutionary algorithms and polynomial interpolation in ship evolutionary trajectory planning method. Evolutionary algorithms allows to find a coIlision free trajectory in real time, while polynomial interpolation allows to model smooth trajectory which keeps continuity of velocity and acceleration values along path. Combination of this two methods allows to find trajectory, which under some assumptions,...

  This article presents the use of a multi-population distributed evolutionary algorithm for path planning in navigation situation. The algorithm used is with partially exchanged population and migration between independently evolving populations. In this paper a comparison between a multi-population and a classic single-population algorithm takes place. The impact on the ultimate solution has been researched. It was shown that using...

  Artykuł prezentuje implementację mechanizmu niszowania do ewolucyjnej metody wyznaczania zadanej trajektorii statku. W metodzie proponowane jest porównywanie różnorodności osobników w oparciu o fizyczną odległość między trajektoriami. Badania pokazują, że takie podejście zwiększa efektywność eksploracji przestrzeni rozwiązań dzięki czemu osiąga się poprawę końcowej wartości funkcji przystosowania. Problem poszukiwania ścieżki przejścia...

  - Year 2013

  This paper presents the concept of the niching mechanism in the evolutionary method of path planning. The problem is considered based on the example of a ship path planning. In this method the diversity of individuals is tested in respect to their physical distance, not the fitness function value. The researches show that such an approach increases effectiveness of solution space exploration, what results in a final solution with...
