A new suffix tree similarity measure for document clustering
In this paper, we propose a new similarity measure to compute the pairwise similarity of text-based documents based on suffix tree document model. By applying the new suffix tree ...

Approximating Optimal Binary Decision Trees
Abstract. We give a (ln n + 1)-approximation for the decision tree (DT) problem. An instance of DT is a set of m binary tests T = (T1, . . . , Tm) and a set of n items X = (X1, . ....

Understanding Search Trees via Statistical Physics
We study the random m-ary search tree model (where m stands for the number of branches of the search tree), an important problem for data storage in computer science, using a varie...

K-NCC: Stability Against Group Deviations in Non-cooperative Computation
A function is non-cooperative computable [NCC] if honest agents can compute it by reporting truthfully their private inputs, while unilateral deviations by the players are not bene...
