deterministic finite tree automaton


Definition: A deterministic finite state machine that accepts finitary trees rather than just strings. The tree nodes are marked with the letters of the alphabet of the automaton, and the transition function encodes the next states for each branch of the tree. The acceptance condition is modified accordingly.

Also known as DFTA.
