complexity, in science, field of study devoted to the process of self-organization. The basic concept of complexity is that all things tend to organize themselves into patterns, e.g., ant colonies, immune systems, and human cultures; further, they go through cycles of growth, mass extinction, regeneration, and evolution. Complexity looks for the mathematical equations that describe the middle ground between equilibrium (see staticsstatics,
branch of mechanics concerned with the maintenance of equilibrium in bodies by the interaction of forces upon them (see force). It incorporates the study of the center of gravity (see center of mass) and the moment of inertia.

Because complex systems typically cross the boundaries of traditional disciplines, the study of complexity is an interdisciplinary science.

ComplexityConsisting of various parts united or connected together, formed by a combination of different elements; intricate, interconnecting parts that are not easily disentangled.complexity[kəm′plek·səd·ē] (computer science) The number of elementary operations used by a program or algorithm to accomplish a given task. complexity (algorithm)The level in difficulty in solving mathematicallyposed problems as measured by the time, number of steps orarithmetic operations, or memory space required (called timecomplexity, computational complexity, and space complexity,respectively).
The interesting aspect is usually how complexity scales withthe size of the input (the "scalability"), where the size ofthe input is described by some number N. Thus an algorithmmay have computational complexity O(N^2) (of the order of thesquare of the size of the input), in which case if the inputdoubles in size, the computation will take four times as manysteps. The ideal is a constant time algorithm (O(1)) orfailing that, O(N).
