Kolmogorov Structure Function - Contemporary Definition

Contemporary Definition

It is discussed in. It is extensively studied in where also the main properties are resolved. The Kolmogorov structure function can be written as

where x is a binary string of length n with where S is a contemplated model (set of n-length strings) for x, is the Kolmogorov complexity of S and is a nonnegative integer value bounding the complexity of the contemplated S's. Clearly, this function is nonincreasing and reaches for where c is the required number of bits to change x into and is the Kolmogorov complexity of x.

Famous quotes containing the words contemporary and/or definition:

    Eclecticism is the degree zero of contemporary general culture: one listens to reggae, watches a western, eats McDonald’s food for lunch and local cuisine for dinner, wears Paris perfume in Tokyo and “retro” clothes in Hong Kong; knowledge is a matter for TV games. It is easy to find a public for eclectic works.
    Jean François Lyotard (b. 1924)

    Perhaps the best definition of progress would be the continuing efforts of men and women to narrow the gap between the convenience of the powers that be and the unwritten charter.
    Nadine Gordimer (b. 1923)
