Diversity Variety of choices, in which evolution thrives. A key resource for an evolutionary process. The other resource for evolution is its own increasing order.
DNA Deoxyribonucleic acid; the building blocks of all organic life-forms. In the twenty-first century, intelligent life-forms will be based on new computational technologies and nanoengineering.
DNA computing A form of computing, pioneered by Leonard Adleman, in which DNA molecules are used to solve complex mathematical problems. DNA computers allow trillions of computations to be performed simultaneously.

Einstein’s theory of relativity
Refers to two of Einstein’s theories. Einstein’s Special Theory of Relativity postulates the speed of light as the fastest speed at which we can transmit information. Einstein’s General Theory of Relativity deals with the effects of gravity on the geometry of space. Includes the formula E=mc

(energy equals mass times the speed of light squared), which is the basis of nuclear power.

Entropy In thermodynamics, a measure of the chaos (unpredictable movement) of particles and unavailable energy in a physical system of many components. In other contexts, a term used to describe the extent of randomness and disorder of a system.
Evolution A process in which diverse entities (sometimes called organisms) compete for limited resources in an environment, with the more successful organisms able to survive and reproduce (to a greater extent) into subsequent generations. Over many such generations, the organisms become better adapted at survival. Over generations, the order (suitability of information for a purpose) of the design of the organisms increases, with the purpose being survival. In an “evolutionary algorithm” (see below), the purpose may be defined to be the discovery of a solution to a complex problem. Evolution also refers to a theory in which each life-form on Earth has its origin in an earlier form.
Evolutionary algorithm Computer-based problem-solving systems that use computational models of the mechanisms of evolution as key elements in their design.
Experiments in Musical Intelligence (EMI) A computer program that composes musical scores. Created by the composer David Cope.

Foglet A hypothetical robot that consists of a human-cell-sized device with twelve arms pointing in all directions. At the end of the arms are grippers so that the Foglets can grasp one another to form larger structures. These nanobots are intelligent and can merge their computational capacities with one another to create a distributed intelligence. Foglets are the brainchild of J. Storrs Hall, a Rutgers University computer scientist.
Free will Purposeful behavior and decision making. Since the time of Plato, philosophers have explored the paradox of free will, particularly as it applies to machines. During the next century, a key issue will be whether machines will evolve into beings with consciousness and free will. A primary philosophical issue is how free will is possible if events are the result of the predictable—or unpredictable—interaction of particles. Considering the interaction of particles to be unpredictable does not resolve the paradox of free will because there is nothing purposeful in random behavior.
General Problem Solver (GPS) A procedure and program developed by Allen Newell, J. C. Shaw, and Herbert Simon. GPS attains an objective by using recursive search and by applying rules to generate the alternatives at each branch in the recursive expansion of possible sequences. GPS uses a procedure to measure the “distance” from the goal.
Genetic algorithm A model of machine learning that derives its behavior from a metaphor of the mechanisms of evolution in nature. Within a program, a population of simulated “individuals” are created and undergo a process of evolution in a simulated competitive environment.
Genetic programming The method of creating a computer program using genetic or evolutionary algorithms. See Evolutionary algorithm; Genetic algorithm.
