In the formula, D represents the distance between the whale and its prey, x represents the best position vector, b represents a constant used to define the shape of the spiral, and l is a random number in (-1, 1)
D represents the distance between the whale and the prey, x represents the best position vector available, b indicates the shape of a constant to define the screw, and l is a random number in (-1, 1).
Where D is the distance between whale and prey, X is the best position vector at present, B is a constant to define the shape of spiral, and l is the random number in (- 1,1).<br>
