How to decide Functionality of Compositions of Top-Down Tree Transducers
Sebastian Maneth, Helmut Seidl, and Martin Vu
TL;DR
This paper proves that determining the functionality of composed top-down tree transducers is decidable by reducing the problem to a single transducer with look-ahead, advancing theoretical understanding in tree transformation analysis.
Contribution
It introduces a method to decide functionality of composed top-down tree transducers by reduction to a single transducer with look-ahead, a novel theoretical result.
Findings
Functionality of compositions is decidable.
Reduction to single transducer with look-ahead is effective.
Advances theoretical understanding of tree transducer compositions.
Abstract
We prove that functionality of compositions of top-down tree transducers is decidable by reducing the problem to the functionality of one top-down tree transducer with look-ahead.
