Abstract

A topological method is given for obtaining lower bounds for the height of algebraic decision trees. The method is applied to the knapsack problem where an Ω(n2) bound is obtained for trees with bounded-degree polynomial tests, thus extending the Dobkin-Lipton result for linear trees. Applications to the convex hull problem and the distinct element problem are also indicated. Some open problems are discussed.

    Linear decision trees and algebraic decision and computation trees were studied most intensively. Lower bounds on the complexity were obtained in [2,4,5] for linear decision trees, in [19–21] for algebraic decision trees, in [1,6] for algebraic computation trees, and in [7] for Pfaffian computation trees. Upper bounds on the complexity were obtained in [3,8,10] for linear decision trees and in [17] for quasilinear decision trees that includes linear decision trees and some kinds of algebraic decision trees.
