What do the step sizes do in Evolution Strategies? O 1. It dictates how much or how little the height of a child in the fitness landscape differs from its parent. 2. They constrain how much or how little a given value in the genotype is mutated, when a parent genotype spawns a child genotype. 3. It dictates how much or how little the height of a parent in the fitness landscape differs from its children. O 4. It dictates where two parent genotypes should be cut into two pieces, in preparation for sexual recombination into two new child genotypes
