NK model of fitness landscapes
E1002070
The NK model of fitness landscapes is a theoretical framework in evolutionary biology and complex systems that represents how the fitness of an organism depends on interactions among multiple genes, allowing the study of rugged adaptive landscapes and evolutionary dynamics.
