Fix dimension broadcasting issue in particle random reset mechanism

[424635328]

Hi @aliasgharheidaricom , thank you for sharing the code for FATA.

While studying the implementation, I noticed a potential issue in the particle reset mechanism (Line [89] in FATA.m).

The Issue:
The current code uses:

Flight(i,:) = (ub-lb).*rand+lb;

In MATLAB, rand returns a scalar. This causes the same random value to be broadcasted to all dimensions of Flight(i,:). As a result, the particle updates identically across all dimensions (moving diagonally), which severely restricts the exploration capability of the algorithm.

We can observe it from a two-dimensional perspective

snap1 (x=y)

Suggested Fix:
It should likely generate a random vector matching the dimension size:

Flight(i,:) = (ub-lb).*rand(1,dim)+lb;

snap2 (random)

Verification:
I tested both versions. The original code generates correlated coordinates, while the fixed version ensures independent randomization for each dimension.

Thanks again for your great work!
