Questions of decidability for context-free chain code picture languages,om the current point" for letter u (d,r,l, resp.) and "lift (sink) the pen" for ↑ (↓). The set of unit lines traversed with sunk pen is the picture described. A set of pictures given by a set of picture descriptions generated by a context-free grammar is called a context-free (chain code) picture la

Chomsky hierarchy and communication complexity,ls of both hierarchies. There are hard languages according to Chomsky hierarchy that belong to the lowest level in communication complexity hierarchy. On the other hand there is a deterministic linear language that requires the highest (linear) communication complexity. This is the main result becau

A partially persistent data structure for the set-union problem with backtracking, are possible. A partially persistent data structure is presented which maintains a partitions of an . set and performs each ., each . and each search in the past in . time per operation, at the same time allowing to backtrack, over the sequence of . in costant time. The space complexity of such a s

A note on the computational complexity of bracketing and related problems,complete problem. This problem is related to problems on random walks, planar triangulations of convex polygons and to the problem of comparison of two (labeled) rooted trees. The latter problem is studied with the connection to cluster analysis. Finally, some polynomially solvable classes of bracke
