Kolmogorov complexity

also called algorithmic complexity

timeless3 connections

the true length of the shortest description of a thing — and it cannot be computed

the formal statement
K(x) = the length of the shortest program that outputs x

Where it sits

The prism has six jobs across and eight layers down. Its primary cell is measure × L0. Hatched cells cannot exist — a GPU does not learn, an institution does not infer.

What must come first — and what it unlocks

Left to right is reading order, derived from the prerequisite_of edges. Nothing here is hand-ordered: the diagram is the graph.

nothing comes first — this is a starting pointKolmogorov complexitynothing depends on it yet — a leaf in the reading order

This page is a projection of one node in src/data/concepts.ts. It has no prose file of its own — 521 declared edges produce all 340 of these pages. Edit an edge and both endpoints change.
