Operator precedence languages, designated as Floyd’s Languages (FL) to honor their inventor, are a classical deterministic context-free family. FLs are known to be a boolean fami...
One-way and two-way cellular language acceptors with restricted nondeterminism are investigated. The number of nondeterministic state transitions is regarded as limited resource wh...
The theory of two-dimensional languages, generalizing formal string languages, was motivated by problems arising from image processing and models of parallel computing. Weighted au...
This paper studies a novel paradigm for learning formal languages from positive and negative examples which consists of mapping strings to an appropriate highdimensional feature s...
Abstract. We give a characterization, in terms of computational complexity, of the family Rec1 of the unary picture languages that are tiling recognizable. We introduce quasi-unary...
