Great job Mustapha, this is an excellent introduction to the PSO, however, I have a question regarding the damping parameter. In this problem you already know the optimal solution and thus you have modified the code to include a damping effect. The question is : what if I have no idea about the optimal solution ? Should I just add it? Cheers

to get modified result you can use damping with other value.

hallow Sir I've watched the video which was really interesting and useful The problem which guided me to this channel is not yet explained... and if you allow me to suggest it as a future lecture ... i will be so grateful if you respond... the problem is that how to connect an algorithm with a neural network step by step starting from downloading the ready code from MATWORKS webpage and extract the contains to a folder then start connect the algorithm with the neural network by changing the fitness function and use the output of one of them as an input to the other, which might be noted as optimization (since i didn't find any solution on KZitem which can be considered as source for real learning which leads to ability to solve any connection problem such that you need to apply different algorithms or other neural network for the same system)

Great video!!! I have a question about the VarMin and VarMax variables. These variables define the upper and lower bound. But when I define for example: VarMin = 0 VarMax = 5 nVar = 5 Then of course I get for the GlobalBest a vector with 5 columns. For example: Position: [3.7542e-04 -8.0293e-04 -0.0011 1.1266e-04 1.5088e-04] How is this possible? There are negative values. And I defined the minimum boundary with zero. I hope someone can help me with my understanding problem
