The evolution process represented as a sequence $\left\{D\right(t):t\in \mathbb{N}\}$ of distributions and a sequence $\left\{P\right(t):t\in \mathbb{N}\}$ of vectors in ${\mathcal{G}}^k$ (concrete populations) that depend on each other via various mappings. Each mapping is constructed by a composition of evolutionary operators that we characterize and classify in this work.
