Saeed Nezhadhosein‎; Reza Ghanbari; Khatere Ghorbani-Moghadam

Volume 8, Issue 1 , June 2023, , Pages 1-17

  In this paper, we solve a class of nonlinear optimal control problems using a hybrid genetic algorithm (HGA) and a direct method based on the Haar wavelets where the performance index is Bolza-form and the dynamic system is linear‎. ‎First‎, ‎we change the problem by using HWs to a static ...  Read More
