| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | The authors recently proposed an SQL-based language CombSQL+ for specifying combinatorial optimization problems, and showed a solving method that uses an SMT solver. This method has an advantage that problem constraints are written in ordinary SQL queries, and hence it enables us an intuitive specification. In order to generate constraints to be solved by an SMT solver from a specification, it uses SQL queries extended for constrained tables, each of which represents a set of tables. Current extended queries, however, does not cover full-SQL query facilities, hence for this we need to develop a complex SQL-engine for constrained tables. This paper proposes a generation method of an ordinary SQL query, whose execution by an existing SQL-engine causes constraints for SMT solvers. Here, a key technique is the use of user-definable functions that may cause side-effects allowed in the database system SQLite. |
