Organisms, road networks, and computer chips all share a design challenge related to the problem of delivering resources through a network to every node in the system. With design optimizations, how does the total size of the resource distribution system (the vascular system) of mammals scale as the mass of the mammal increases?

In the readings in An Introduction to Genetic Algorithms, Mitchell describes the building blocks hypothesis. This hypothesis states the following, “Selection increasingly focuses the search on subsets of the search space with estimated above average fitness, beginning with low-order schema and over time detecting biases in high-order schema by combining lower-order schemas.” Which of the following operations is necessary for this hypothesis to be applied to genetic algorithms?
