WebGP Search Algorithm. We provide a standard GP search algorithm with the capabilities for co-evolution, as well as asynchronous individual evaluation. Whether the search algorithm uses co-evolution or asynchronous individual evaluation is determined by the user-provided fitness function. See here for more information on how to define a fitness ... A fitness function is a particular type of objective function that is used to summarise, as a single figure of merit, how close a given design solution is to achieving the set aims. Fitness functions are used in evolutionary algorithms (EA), such as genetic programming and genetic algorithms to guide simulations towards optimal design solutions. In the field of EAs, each design solution is commonly represented as a string of numbers (referr… economic value added is also referred to as
