Main Page | See live article | Alphabetical index Complexity There are different senses of complexity: In computer science, the study of how much time and memory a computer algorithm may take is the field of computational complexity theory. Complexity is often used as a shorthand for the field that developed in the late 1980s around the use of mathematical and computational modeling of biological, economic and technological systems known as "complex systems" (sometimes complex adaptive systems).
