Abstract [en]

We introduce a generalization of tree-based generators called delegation networks. These make it possible to generate objects such as strings, trees, graphs, and pictures in a modular way by combining tree-based generators of several types. Our main result states that, if all underlying tree generators generate regular tree languages (or finite tree languages), then the tree-generating power of delegation networks is the same as that of context-free tree grammars working in IO mode.
