what do you mean by complexity?

Answer 1

The complexity of something involves the need to understand more than one idea or principle.It can exist in itself - such as in a very long sentence - and/or it can exist in its implications. An example of a simple question that requires a complex answer is "How do you feel about George?"

Answer 2

Complex -- the root word -- has a number of definitions.

It could mean:
1/ An intricate, involved plan, scheme, design or creation.
2/ A collection of constructions or buildings of diverse purpose created to harmoniously blend and or interact.
3/ A very focused mindset, preoccupation or obsession with a particular subject.

Thus an architect who has a strong penchant for designing ONLY the minutia of shopping malls could be said to have a complex complex complex!

Answer 3

Complexity in general usage is the opposite of simplicity. Complexity in specific usage is the opposite of independence, while complication is the opposite of simplicity.

Complexity in general means:

The state of being complex; intricacy; entanglement.
That which is complex; intricacy; complication.

[edit] Specific forms of complexity
In several scientific fields, "complexity" has a specific meaning :

In computational complexity theory, the time complexity of a problem is the number of steps 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 problems by complexity class (such as P, NP ... ) such analysis also exists for space, that is, the memory used by the algorithm.
In algorithmic information theory, the Kolmogorov complexity (also called descriptive complexity or algorithmic entropy) of a string is the length of the shortest binary program which outputs that string.
In information processing, complexity is a measure of the total number of properties transmitted by an object and detected by an observer. Such a collection of properties is often referred to as a state.
In physical systems, complexity is a measure of the probability of the state vector of the system. This is often confused with entropy, but is a distinct Mathematical analysis of the probability of the state of the system, where two distinct states are never conflated and considered equal as in statistical mechanics.
In mathematics, Krohn-Rhodes complexity is an important topic in the study of finite semigroups and automata.
There are different specific forms of complexity:

In the sense of how complicated a problem is from the perspective of the person trying to solve it, limits of complexity are measured using a term from cognitive psychology, namely the hrair limit.
Specified complexity is a term used in intelligent design theory, first coined by William Dembski.
Irreducible complexity is a term used in arguments against the generally accepted theory of biological evolution, being a concept popularized by the biochemist Michael Behe.
Unruly complexity denotes situations that do not have clearly defined boundaries, coherent internal dynamics, or simply mediated relations with their external context, as coined by Peter Taylor.

Answer 4

Hey Amrin, COMPLEX = "Complicated or intricate as to be hard to understand or deal with"
COMPLEXITY = "The state or quality of being complex".
Ex: "the complexity of urban life"
COMPLICATED = "Difficult to analyze, understand or explain"
Ex: "A complicated problem"

Answer 5

How complex, so how complicated is it. To what degree is it simple, or difficult with lots of different this to say about it.
