Complexity characterises the behaviour of a system or model whose components interact in multiple ways and follow local rules, meaning there is no reasonable higher instruction to define the various possible interactions. 1The stem of the word complexity complex combines the Latin roots com meaning together and plex meaning woven. Contrast complicated where plic meaning folded refers to many layers. A complex system is thereby characterised by its inter dependencies, whereas a complicated system is characterised by its layers. Complexity is generally used to characterize something with many parts where those parts interact with each other in multiple ways, culminating in a higher order of emergence greater than the sum of its parts. Just as there is no absolute definition of intelligence, there is no absolute definition of complexity the only consensus among researchers is that there is no agreement about the specific definition of complexity. However, a characterization of what is complex is possible. 2 The study of these complex linkages at various scales is the main goal of complex systems theory. Science as of 2. 01. Zayed et al. 3 reflect many of these. Neil Johnson states that even among scientists, there is no unique definition of complexity and the scientific notion has traditionally been conveyed using particular examples. Ultimately Johnson adopts the definition of complexity science as the study of the phenomena which emerge from a collection of interacting objects. 4OvervieweditDefinitions of complexity often depend on the concept of a confidential system a set of parts or elements that have relationships among them differentiated from relationships with other elements outside the relational regime. Many definitions tend to postulate or assume that complexity expresses a condition of numerous elements in a system and numerous forms of relationships among the elements. However, what one sees as complex and what one sees as simple is relative and changes with time. Warren Weaver posited in 1. Phenomena of disorganized complexity are treated using probability theory and statistical mechanics, while organized complexity deals with phenomena that escape such approaches and confront dealing simultaneously with a sizable number of factors which are interrelated into an organic whole. 5 Weavers 1. The approaches that embody concepts of systems, multiple elements, multiple relational regimes, and state spaces might be summarized as implying that complexity arises from the number of distinguishable relational regimes and their associated state spaces in a defined system. Some definitions relate to the algorithmic basis for the expression of a complex phenomenon or model or mathematical expression, as later set out herein. Disorganized vs. organizededitOne of the problems in addressing complexity issues has been formalizing the intuitive conceptual distinction between the large number of variances in relationships extant in random collections, and the sometimes large, but smaller, number of relationships between elements in systems where constraints related to correlation of otherwise independent elements simultaneously reduce the variations from element independence and create distinguishable regimes of more uniform, or correlated, relationships, or interactions. Weaver perceived and addressed this problem, in at least a preliminary way, in drawing a distinction between disorganized complexity and organized complexity. In Weavers view, disorganized complexity results from the particular system having a very large number of parts, say millions of parts, or many more. Though the interactions of the parts in a disorganized complexity situation can be seen as largely random, the properties of the system as a whole can be understood by using probability and statistical methods.

A prime example of disorganized complexity is a gas in a container, with the gas molecules as the parts. Some would suggest that a system of disorganized complexity may be compared with the relative simplicity of planetary orbits the latter can be predicted by applying Newtons laws of motion. Of course, most real world systems, including planetary orbits, eventually become theoretically unpredictable even using Newtonian dynamics as discovered by modern chaos theory. 7Organized complexity, in Weavers view, resides in nothing else than the non random, or correlated, interaction between the parts. These correlated relationships create a differentiated structure that can, as a system, interact with other systems. The coordinated system manifests properties not carried or dictated by individual parts. The organized aspect of this form of complexity vis a vis to other systems than the subject system can be said to emerge, without any guiding hand. The number of parts does not have to be very large for a particular system to have emergent properties. A system of organized complexity may be understood in its properties behavior among the properties through modeling and simulation, particularly modeling and simulation with computers. An example of organized complexity is a city neighborhood as a living mechanism, with the neighborhood people among the systems parts. 8Sources and factorseditThere are generally rules which can be invoked to explain the origin of complexity in a given system. The source of disorganized complexity is the large number of parts in the system of interest, and the lack of correlation between elements in the system.
