This is a new, simple non-linear solver that uses a swarm
(population) to do global optimization. It uses two algoritms -
Particle Swarm Optimization (PSO) or Differential Evolution (DE)
to find a (non-optimal) solution.
It is experimental as not all functions are implemented and it
needs a lot more testing so that it performs well.
