Hello, Every Body
Am studying evolutionnary algorithm convergence,
now am at the BAT algorithm .
I have tested the source code of this algorithm using the well-known 23 benchmarked functions , but in vain it seems that its convergence is very bad for all the functions.
After reading its related paper i have found that:
this algorithm is tested only on 5 functions.!!
* among these 5 functions there are only 3 functions among the 23 functions of which most metaheuristic algorithms are tested.
* It seems to me that BAT algorithm, as it is never converges, !! unless there is an error in the shared source code .
here is the download link:
https://www.mathworks.com/matlabcentral/fileexchange/37582-bat-algorithm-demo
I tried the two BAT codes, the two do not converge !!!!
any advice , any correction are highly appreciated

Hello, I'm also studying bat algorithm recently. I found the same problem with you. Do you know the reason

yes , after i studied so many algorithms !!
I know the reason !
This is what we call
"Scientific research fraud"
the algorithm has a very bad convergence rate , or also you can say : it never converge !!,
and so many researcher pretend that PSO is special case of Bat !!! ,
while, the reality it is the complete opposite.
