Tierra is a computer simulation developed by ecologist Thomas S. Ray in the early 1990s in which computer programs compete for time (central processing unit time) and space (access to main memory). In this context, the computer programs in Tierra are considered to be evolvable and can mutate , self-replicate and recombine .
Natural Selection is a hybrid FPS/RTS that pits Marines against Aliens ("the Kharaa"), played primarily in the first-person perspective, within the confines of large atmospheric maps of spaceships or space stations, which have been invaded by the Kharaa. There are two game modes in Natural Selection: Classic and Combat.
The success of Natural Selection convinced Cleveland to start work on a commercial sequel to the game: Natural Selection 2. Soon after, Cleveland founded Unknown Worlds Entertainment as a commercial computer games studio. Although the casual games market is not the intended direction of Unknown Worlds, Zen of Sudoku, a casual puzzle computer ...

The program aims to demonstrate that the preservation of small changes in an evolving string of characters (or genes) can produce meaningful combinations in a relatively short time as long as there is some mechanism to select cumulative changes, whether it is a person identifying which traits are desirable (in the case of artificial selection) or a criterion of survival ("fitness") imposed by ...
A cellular evolutionary or memetic algorithm uses a topological neighbouhood relation between the individuals of a population for restricting the mate selection and by that reducing the propagation speed of above-average individuals. The idea is to maintain genotypic diversity in the poulation over a longer period of time to reduce the risk of ...
The term natural selection is most often defined to operate on heritable traits, because these directly participate in evolution. However, natural selection is "blind" in the sense that changes in phenotype can give a reproductive advantage regardless of whether or not the trait is heritable.
Natural Selection 2 is a multiplayer video game which combines first-person shooter and real-time strategy rules. It is set in a science fiction universe in which a human team fights an alien team for control of resources and territory in large and elaborate indoor facilities. [1] It is the sequel to Natural Selection.
