| Abstract(in English) | A simple logic programming language for reasoning about sequences is defined and computational complexity of the basic problems for the language is investigated. The domain of a predicate is the set of finite sequences (strings) over an alphabet with concatenation as the only interpreted operator. A program in this language is a finite set of clauses. The paper mainly investigates decidability/complexity of the logical consequence problem. First, the problem is shown to be undecidable. Then, the paper introduces a subclass of programs, called simple productive systems (SPSs for short). The paper investigates how the complexity of the problem for SPS depends on syntactical restrictions such as right-linearity and non-erasingness. |
