abstract = "We use evolutionary computation (EC) to automatically
find problems which demonstrate the strength and
weaknesses of modern search heuristics. In particular
we analyse Particle Swarm Optimization (PSO) and
Differential Evolution (DE). Both evolutionary
algorithms are contrasted with a robust deterministic
gradient based searcher (based on Newton-Raphson). The
fitness landscapes made by genetic programming (GP) are
used to illustrate difficulties in GAs and PSOs thereby
explaining how they work and allowing us to devise
better extended particle swarm systems (XPS).",
