The SS approach involves different procedures allowing to generate the initial
population, to build and update the reference set, to combine the solutions of such
set, to improve the constructed solutions, and so on.
++++SS uses explicitly strategies for
both search intensification and search diversification.
++ It integrates search components
from P-metaheuristics and S-metaheuristics.
+++The algorithm starts with a set of diverse
solutions, which represents the reference set (initial population) (see Algorithm 3.10).
+++
This set of solutions is evolved by means of recombination of solutions as well as by
the application of local search (or another S-metaheuristic).
