Sophistication (complexity theory)
From HandWiki
In algorithmic information theory, sophistication is a measure of complexity related to algorithmic entropy. When K is the Kolmogorov complexity and c is a constant, the sophistication of x can be defined as[1]
The constant c is called significance. The S variable ranges over finite sets.
Intuitively, sophistication measures the complexity of a set of which the object is a "generic" member.
