Some results on decision trees with relations to computational trees
- 129 Downloads
In this paper we have shown some results for decision trees with tests from the essentially wider class of functions than the polynomials of bounded degree.
We introduced the notion of functions r-distant to Rd[x] and have shown how starting from decision trees we can derive lower bounds in the model of computation trees. This relation suggests an uniform approach to lower bound proving in decision and computational tree models.
