(June 2013) Complexity characterises the behaviour of a or whose components interact in multiple ways and follow local rules, meaning there is no reasonable higher instruction to define the various possible interactions. The 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 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'. The study of these complex linkages at various scales is the main goal of. As of 2010 takes a number of approaches to characterizing complexity; Zayed et al. Reflect many of these.
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'. Contents • • • • • • • • • • • • • • • • • Overview [ ] Definitions of complexity often depend on the concept of a confidential ' – 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.
Posited in 1948 two forms of complexity: disorganized complexity, and organized complexity. 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'. Weaver's 1948 paper has influenced subsequent thinking about complexity. 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. Organized [ ] One 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 Weaver's 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) of planetary orbits – the latter can be predicted by applying. Of course, most real-world systems, including planetary orbits, eventually become theoretically unpredictable even using Newtonian dynamics; as discovered by modern. Organized complexity, in Weaver's 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 and, particularly. An example of organized complexity is a city neighborhood as a living mechanism, with the neighborhood people among the system's parts. Sources and factors [ ] There 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. In the case of self-organizing living systems, usefully organized complexity comes from beneficially mutated organisms being selected to survive by their environment for their differential reproductive ability or at least success over inanimate matter or less organized complex organisms. 's treatment of ecosystems. Complexity of an object or system is a relative property.
For instance, for many functions (problems), such a computational complexity as time of computation is smaller when multitape are used than when Turing machines with one tape are used. Allow one to even more decrease time complexity (Greenlaw and Hoover 1998: 226), while inductive Turing machines can decrease even the complexity class of a function, language or set (Burgin 2005). This shows that tools of activity can be an important factor of complexity. Varied meanings [ ] In several scientific fields, 'complexity' has a precise meaning: • In, the required for the execution of is studied. The most popular types of computational complexity are the time complexity of a problem equal to the number of steps that it takes to solve an instance of the problem as a function of the (usually measured in bits), using the most efficient algorithm, and the space complexity of a problem equal to the volume of the used by the algorithm (e.g., cells of the tape) that it takes to solve an instance of the problem as a function of the size of the input (usually measured in bits), using the most efficient algorithm. This allows to classify computational problems by (such as, etc.). An axiomatic approach to computational complexity was developed.
It allows one to deduce many properties of concrete computational complexity measures, such as time complexity or space complexity, from properties of axiomatically defined measures. • In, the (also called descriptive complexity, algorithmic complexity or algorithmic entropy) of a is the length of the shortest binary that outputs that string. Is a practical application of this approach. Different kinds of Kolmogorov complexity are studied: the uniform complexity, prefix complexity, monotone complexity, time-bounded Kolmogorov complexity, and space-bounded Kolmogorov complexity. An axiomatic approach to Kolmogorov complexity based on (Blum 1967) was introduced by Mark Burgin in the paper presented for publication.
The axiomatic approach encompasses other approaches to Kolmogorov complexity. It is possible to treat different kinds of Kolmogorov complexity as particular cases of axiomatically defined generalized Kolmogorov complexity. Instead of proving similar theorems, such as the basic invariance theorem, for each particular measure, it is possible to easily deduce all such results from one corresponding theorem proved in the axiomatic setting. This is a general advantage of the axiomatic approach in mathematics. The axiomatic approach to Kolmogorov complexity was further developed in the book (Burgin 2005) and applied to software metrics (Burgin and Debnath, 2003; Debnath and Burgin, 2003). • In, complexity is a measure of the total number of transmitted by an object and detected by an.
Such a collection of properties is often referred to as a. • In, complexity is a measure of the of the of the system. Adobe Premiere Project Manager Unknown Error 0xe8000065 there. This should not be confused with; it is a distinct mathematical measure, one in which two distinct states are never conflated and considered equal, as is done for the notion of entropy in. • In, is an important topic in the study of finite and. • In complexity is the product of richness in the connections between components of a system, and defined by a very unequal distribution of certain measures (some elements being highly connected and some very few, see ).
• In, is a measure of the interactions of the various elements of the software. This differs from the computational complexity described above in that it is a measure of the design of the software. • In sense – Abstract Complexity, is based on visual structures It is complexity of binary string defined as a square of features number divided by number of elements (0's and 1's). Features comprise here all distinctive arrangements of 0's and 1's. Though the features number have to be always approximated the definition is precise and meet intuitive criterion.

Vastly present in the literature, the word “complex” seems to stand for a supernatural force supposedly responsible for disturbances, a scary ghost haunting projects. With no absolute definition of what complexity means, the only consensus among researchers is that there is no agreement about the specific definition of complexity [66]. However, a characterization of what is complex is possible.
