The syntactic inference problem for dol-sequences,iven words; and also of actually finding any such grammars. In this paper, the problem is considered for DOL-systems. The stress is on the second, constructive, part of the problem. The initial information may have various forms. Most of the results deal with cases in which.— the words are given as

Hypomania

Free groups in Lindenmayer systems,there exists a locally catenative equation in the free group which defines the DOL sequence. An algorithm is given which finds the generators of the free group if it is finitely generated..A conjecture is stated in terms of the existence of a certain group. The conjecture implies the solvability of

蓋他為秘密

Structured OL-systems,ganisms and structurally dependent developments. It is shown that a restricted version of SOL-systems is equivalent to codings (length-preserving homomorphisms) of OL-Languages. The properties of unrestricted SOL-systems are then studied. It is for example shown that the languages generated by them

不能妥協(xié)

Context in parallel rewriting,ems are introduced in this paper. We investigate the generative power of these new types of context sensitive parallel rewriting systems and we compare it to the generative power of TOL-systems [81], L-systems with interaction [92], regular grammars and context sensitive grammars.

ial cells are unique in that they are interconnected to each other via gap junctions and thus act as an electrical syncytium, a vast number of important cellular receptors and signal transduction pathways allow individual cells to receive and respond to various signals. These receptors and signal tr
