Enhanced bonobo optimizer for optimizing dynamic photovoltaic models
(Wydawnictwa AGH, 2024) Eid, Heba F.; Cuevas, Erik
Bonobo optimizer (BO) is a novel metaheuristic algorithm motivated by the social behaviour of the bonobos. This paper presents a quantum behaved bonobo optimization algorithm (QBOA) employing an innovative metaheuristic based on the reproductive strategies and social behavior of bonobos. Whereby, the quantum mechanics are embedded into the bonobo optimizer to direct the search agents through the search space. Accordingly, under this quantum-behaved movement, the proposed QBOA’s exploitation capability is promoted. The performance of the proposed QBOA is exhibited on CEC2005 and CEC2019 benchmarks. Moreover, the QBOA algorithm was adapted to optimize the dynamic photovoltaic models parameters. QBOA exhibits the efficiency and adequacy to solve various optimization problems based on experimental and comparison findings, as well as its ability to implement competitive and promising results optimizing dynamic photovoltaic models.

Implementation of the least squares method in determining the parameters of Knothe´s theory
(2014) Witkowski, Wojciech T.
W artykule przedstawiono obecnie stosowaną metodę prognozowania wpływów górniczych w Polsce. Zwrócono uwagę na znaczenie parametrów teorii Knothego oraz konieczność ich wyznaczenia dla różnych warunków górniczo-geologicznych. Przedstawiono propozycję realizacji metody najmniejszych kwadratów do wyznaczenia parametrów teorii z wykorzystaniem równań obserwacyjnych. Zaproponowany algorytm obliczeniowy zaimplementowano w programie Scilab 5.4.1 i przeprowadzono analizę poprawności działania aplikacji. Na koniec wykorzystano program do wyznaczenia parametrów w różnych rejonach górniczych.

The usability of the Nash cascade-submerged cascade rainfall-runoff model with regard to other conceptual models
(Wydawnictwa AGH, 2024) Laskowski, Norbert; Kurnatowski, Jacek
Conceptual hydrological models are an effective tool used to forecast runoff from catchments and assess changes in catchment dynamics. The article presents a modified concept of the Diskin parallel cascade model, with the replacement of one of the cascades with the submerged cascade model – the Nash cascade-submerged cascade model (NCSC2). Considering a watershed as a system where total runoff is determined by amounts of both surface and subsurface runoffs, the use of different model structures as surface and subsurface runoffs is reasonable. Adopting 13 different objective functions, the comparative analysis of NCSC2, Nash cascade, Diskin model, single linear reservoir and submerged reservoir cascade (SC2) models has been carried out in the catchment of six Polish rivers. The research has shown that the use of the submerged cascade as one of the Diskin model cascades positively affects the quality of the model.
