The main idea behind NS is to reward the novelty of the produced solution rather than its progress to the final goal. This idea is inspired by natural evolution. When looking for a successful solution, it is not always obvious the exact steps that should be taken. Natural evolution continuously produces novel forms, with different phenotypes trying to exploit the surrounding environment and adapt to the changes. This has allowed an explosion of life forms on Earth and ignited qualitative leaps forward in the evolution of life. The same process allowed life forms to leave the sea and conquer the land. The extraordinary genesis of eukaryotes became the source of all higher life forms on the planet. All these are examples of rewarding novelty during evolution. At the same time, there is no clear objective or final goal in natural evolution.
