How It Works
The HP (hydrophobic-polar) model simplifies protein folding to a 2D lattice problem.
H
residues prefer to be near other H residues. Each non-sequential H-H contact contributes -1 energy.
Goal:
Fold the chain to minimize energy (maximize H-H contacts).
Auto-fold
uses simulated annealing: random moves at high temperature (accept bad moves), then cooling (only accept improvements).
