How do I simulate a gridlock?

Open this page and use the live Ant Colony Optimization tool below — set your inputs and the simulation runs instantly in your browser using real numerics. No install, no account needed.

Yes. The simulation runs free in your browser. A one-time unlock or a Pro plan adds advanced parameters, saved presets, data import, and clean exports.

Can I use my own numbers?

Absolutely — every input is adjustable, and with data import you can drive a gridlock from your own measurements.

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.

About this simulation

The full Ant Colony Optimization tool models a gridlock with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.
