- Random search — Sampling combinations at random instead of testing all of them. Cheap coverage of a space too large to walk, at the cost of possibly missing the best corner.
- Evolutionary search — Seeding a population of settings, keeping the strongest, then mutating and recombining them over generations to home in on what works.
- Curve fitting — Tuning a strategy until it memorises one stretch of history. It produces beautiful backtests and no future returns, which is why results are held out and re-tested.
