A method for designing FPT-algorithms by means of dynamic programming based on thetree decomposition is investigated. Some problems limiting the application of this methodin practice are pointed. The problem of memory is solved by using a binary tree decompositionof the separator, which reduces the theoretical and the actual size of the dynamicprogramming tables. The technique of tables in the language of relational algebra is described.
