How do I simulate a predator-prey cycle?

Open this page and use the live Tumor Growth 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 predator-prey cycle from your own measurements.

Tumors do not grow exponentially forever — they slow as they outstrip their blood supply. Gompertz and logistic models both bend toward a carrying capacity, with growth fastest early on. This shape guides how treatments are timed. Educational tool, not medical advice.

Governing equation

\frac{d V}{d t} = bV ln \frac{K}{V}, b = 0.05, K = 1000

Reading this result: The Gompertz curve reaches half of its 1000-cell ceiling around day 46; growth is fastest early on and flattens as it nears carrying capacity.
