Evaporation

Simulated ants lay pheromone (cyan) on short routes; trails evaporate over time so good paths reinforce and bad ones fade. The colony collectively finds near-optimal tours of the Traveling Salesman Problem — the green loop is the best so far.

Governing equation

p_{ij} = \frac{τ _{ij}^{α} η _{ij}^{β}}{\sum _{k} τ _{ik}^{α} η _{ik}^{β}}, τ_{ij} \leftarrow (1 - ρ) τ_{ij} + Δ τ_{ij}, α = 1, β = 3, ρ = 0.10

Reading this result: With 15 cities and 20 ants, 10% evaporation balances exploring new edges against reinforcing the best tour found so far.
