# Documentation

A strategy is a choice of (non-empty) frequency tables of possible actions.

nullStrategy :: Strategy a -> Bool Source

liftFrequency :: Frequency a -> Strategy a Source

Strategy where only the actions from the given single frequency table can be picked.

(.|) :: Strategy a -> Strategy a -> Strategy a infixr 2 Source

Strategy with the actions from both argument strategies, with original frequencies.

only :: (a -> Bool) -> Strategy a -> Strategy a Source

Strategy with all actions not satisfying the predicate removed. The remaining actions keep their original relative frequency values.

bestVariant :: Strategy a -> Frequency a Source

When better choices are towards the start of the list, this is the best frequency of the strategy.

renameStrategy :: Text -> Strategy a -> Strategy a Source

Overwrite the description of all frequencies within the strategy.
