Logical depth

From Wikipedia, the free encyclopedia

Logical depth is a measure of complexity devised by Charles H. Bennett based on the computational complexity of an algorithm that can recreate a given piece of information. It differs from Kolmogorov complexity in that it considers the computation time of the algorithm with the shortest length, rather than its length.
