Detailed Description
This class implements the bound handling strategy random forth for the particle swarm optimization.
If a particle would leave the search space, the actual new position is sampled uniformly at random on the part of the segment between the old position and the new position, which is inside the search space bounds.

- Parameters
-
random_forth_mark_dimensions Specifies on which dimensions the velocity adjustment is applied.

Updates the position of the particle p according to the current position and the new (already calculated) velocity.
The new position is calculated by adding the velocity to the position. If the new position would be outside of the search space bounds then the bound handling strategy random forth is activated. Afterwards the specified velocity adjustment is activated with suitable parameters.
- Parameters
-
p The particle, which should be updated.
Implements highprecisionpso::BoundHandling.
