compute the conjugate of a tree
format = A,C,D,E,LR,P,S,Z
Specifies the format of the tree. The default is LR. See Iterator[Trees] for a description of the formats.
The Conjugate command computes the conjugate of a tree. The conjugate of a forest consists of its left-to-right mirror reflection. The conjugate of a tree of a given format is computed by converting it to a forest, reflecting, then converting back to the specified format.
The tree parameter is the tree.
Generate a random tree with four internal nodes in LR format.
L,R ≔ Random⁡4,format=LR
Compute its conjugate.
