Constraint programming techniques are successfully used in various areas of software engineering for industry, commerce, transport, finance etc. Constraint solvers for different data types are applied in validation and verification of programs containing data elements of these types. A general constraint solver for sequences is necessary to take into account this data type in the existing validation and verification tools. In this work, we present an original constraint solver for sequences implemented in CHR and based on T. Frühwirth's solver for lists with the propagation of two constraints: generalized concatenation and size. The applications of the solver (with the validation and verification tool BZTT) to different software engineering problems are illustrated by the example of a waiting room model.
