Detailed Description

Multistart.

The name of this algorithm says it all!! It runs the same algorithm over and over on a random initial population. At the end, the champion will keep memory of the luckiest run. The psuedo algorithm is as follow:

> Select a pagmo::population
> Select a pagmo::algorithm
> Store best individual
> Until termination:
> > Reset the population
> > evolve the population with the pagmo::algorithm
