Atlast found a best video for Grey wolf optimization. Great explanation. Thank you so much.

You are most welcome

@user-yl9ww1xy8q 2 месяца назад

Thanks. How to find the strengths and weaknesses of such algorithms?

@PixyLAB 2 месяца назад

Check algorithm performance using different benchmark test function, or you can apply it on deferent optimization problem and analyze results :)

@othmanaljbory3649 Год назад

You could use it to solve the two-level programming paradigm

@PixyLAB Год назад

We tried but need more time to study two-level programming paradigm. Try to study related research papers.

@karanpathak1752 2 года назад

Very Informative video. Thank You for providing us. My question is, "What is our optimal solution position or fitness value?"

@karanpathak1752 2 года назад

Also, can we make a GWO algorithm to maximize or minimize the cost?

@PixyLAB 2 года назад

Depends on problem. Using fitness function we can calculate fitness values.

Madam, During 11:42 duration , you've derived values of D alpha as 0.6154 and X1 = 0.6361. I failed to understand how did u get those values . Please help me. Rest of the video is wonderful.

how to determine the maximum iteration

@PixyLAB 11 месяцев назад

Hello, we can set maximum iterations own. GWO Python Code || Grey Wolf Optimizer in Python || ~xRay Pixy ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-RcEWFc6DLWE.html

@zollen123 5 месяцев назад

Are a, A and C coefficients different per *wolf* or per *round* ?

@PixyLAB 5 месяцев назад

a linearly decrease 2 to 0. a=2-l*((2)/Maximum Iterations) And A, C values are calculated for each wolf using equations A=2*a*r1-a C=2*r2

Thank you for making this video. I have question here, In the video 7.29 You have said dimension of the variable is 30 but you have not used that is it ?? if you have used that then your population size will be 6 X 30 Matrix is it ?? that means 6 wolf with 30 dimension!!.

@PixyLAB 3 года назад

hello, For simplicity i did that. It was very complicated to explain how it is working with 30 dimension.
