100 Crow Search Algorithm

The next steps, from step 8 to step 32, are repeated for a number of iterations

equal to Iter

max

. In steps 8-19 the initial population of N crows is initialized

using formula 8.3 if the value of a random variable r from [0, 1] is greater than

or equal to AP or using the formula 8.4 otherwise. The first case corresponds

to the situation in which the crow C

i

follows another crow C

j

from the flock

having as main objective the discovery of the memory M

j

of that crow, and

the second case corresponds to the situation in which the new position is

initialized randomly in the D-dimensional search space.
