Run a sweep

A sweep runs the same strategy with many combinations of its settings. You decide, for each setting, whether it is one value or a range.

Turn a setting into a range#

In the Tester, open Parameters. Each setting can stay at one value or become a range with a minimum, a maximum and a step. The range a strategy declares in its file is where the Tester starts.

A setting that a strategy marks as not to be optimised stays at one value. Settings can also depend on each other: a strategy can refuse combinations such as a fast average that is slower than the slow one.

Count what you try#

The number of combinations is the product of the ranges. The panel on the right shows it, with the time and cost it implies, before the run starts. There is a cap on how many values one setting can take in a sweep. See the limits for it and for the other caps a run applies.

Read the result#

A sweep's run page lists the combinations that survived, ranked. Its verdict is about the search as a whole: whether the best of them is likely to be an accident.
