KolmogorovBound

Struct KolmogorovBound 

Source
pub struct KolmogorovBound {
    pub num_vars: usize,
    pub bits: usize,
    pub raw_bits: usize,
    pub tree: StructureTree,
}
Expand description

A certified Kolmogorov upper bound on a Boolean function: the recursive structure decomposition and its total description size, with a re-checkable decode witness. This is a — an UPPER bound only. The kernel-certified Chaitin theorem in this module forbids certifying K(f) > c for any function past budget, so a bound that equals the raw 2ⁿ means “irreducible by this arsenal,” never “incompressible.”

Fields§

§num_vars: usize§bits: usize

K̄(f) — the total description size of the recursive decomposition (a computable upper bound).

§raw_bits: usize

2ⁿ — the cost of storing the truth table outright.

§tree: StructureTree

The recursive decomposition itself — the decode witness.

Implementations§

Source§

impl KolmogorovBound

Source

pub fn ratio(&self) -> f64

K̄(f) / 2ⁿ — → 0 for the algorithmically simplest functions, 1 for the residue.

Source

pub fn is_compressed(&self) -> bool

Whether the decomposition beats storing the truth table.

Source

pub fn verify(&self, truth: &[bool]) -> bool

Re-check the bound: the decomposition must decode back to the exact function.
