Green IS in Education Industry: A Case Studylly-testable (SLT) language of order 2. The family of recognizable picture languages is also defined, using larger . by . tiles, ., by the projection of the corresponding SLT language. A basic measure of the descriptive complexity of a picture language is given by the size of the SLT alphabet using

Grounding of Concept, Indexical, and Name different types to freely commute. We show that balanced regular and .-regular languages can be characterised by syntactic constraints on regular and .-regular expressions and, using the shuffle on trajectories operator, we define grammars for balanced-by-construction expressions with which one can

We show that the universality problem is undecidable for three-state automata by a direct reduction from the .. We also consider other more general acceptance conditions as well as

In order to give concise patterns, we allow the use of subwords on paths in finite graphs. This concept is formalized as subword patterns. Deciding the presence or absence of such a pattern in a

For a state-partition automaton with . states (also called automata with the observer property) the projected language is recognizable with

Furthermore, we give a full classification of the realizable complexities for constraint automata with at most two states and over a ternary alphabet. We find that most constrained problems that are .-complete in general become .-complete. However, there also ex
