Often complicated behaviour of particle swarm and other population based
stochastic optimisers on difficult problems
can be approximated by a simpler techniques on equivalent landscapes.
Here we have used genetic programming to evolve a low pass filter which is
applied to the real problem to give a smoother equivalent problem.
Trace of PSO swarm (red arrows) and its centre (blue box)
Lower blue curve is plot of equivalent landscape on which a hill climber
(lower blue box) tracks center of the swarm.
