-After the encoding of variables, see above, the initial solution point <I>x</I><sub>0</sub> and the initial standard deviation (step-size) σ<sub>0</sub> must be chosen. In a practical application, one often wants to start by trying to improve a given solution locally. In this case we choose a rather small σ<sub>0</sub> (say in [0.001, 0.1], given the <I>x</I>-values "live" in [0,10]). Thereby we can also check, whether the initial solution is possibly a local optimum. When a global optimum is sought-after on rugged or multimodal landscapes, σ<sub>0</sub> should be chosen such that the final desirable location (or at least some of its domain of attraction) is not far outside of <I>x</I><sub>0</sub> ± 2σ<sub>0</sub> in each coordinate. (Remark that in <I>R<SUP>n</SUP></I>, if each boundary domain is in distance σ, then the boundary corner is σ √<span style="text-decoration:overline"><I>n</I></span> away, which poses a slight dilemma for larger <I>n</I>.)
