Lévy Flight
Updated 2026-08-05
INTRODUCTION
English translation pending.
CORE DEFINITION
A Lévy flight is a random walk whose step lengths follow a heavy-tailed power-law distribution, so most steps are short and occasional steps are extremely long. The core claim is that this mixture searches space more efficiently than Brownian motion, whose step lengths decay exponentially and therefore rarely escape a local region. The qualification is that the advantage comes specifically from the heavy tail; ordinary random jumps do not produce the same effect, and the benefit depends on matching jump scale to the problem's scale.
SCAFFOLDING EFFECT
Reduce cognitive load
- Efficient Exploration: Do not always advance at a constant pace; alternate deep local work with occasional large jumps. - Deep Then Jump: Cultivate one field with short steps, and when it stalls, take a decisive long jump into a new area. - Search Design: Mixing a proportion of long steps into a search is what prevents it from getting stuck in a local optimum.
Anchor fast decisions
Step lengths are drawn from a heavy-tailed power-law distribution, so the walker mostly makes short local moves but occasionally travels very far. Because an exponential step distribution rarely escapes a region, the heavy tail is what lets the walker cover large spaces efficiently and avoid being trapped.
