Self-Avoiding Walk

Lattice polymer model — the Flory exponent ν ≈ 3/4 in 2D

Parameters

Self-Avoiding Walk (SAW)
A random walk that cannot revisit lattice sites — models polymer chains.

End-to-end distance scales as:
⟨R²⟩ ~ N^(2ν)

In 2D: ν = 3/4 (Flory)
In 3D: ν ≈ 0.588
In 4D+: ν = 1/2 (simple RW)

When the walk gets trapped, it restarts automatically.
