Best possible bounds on the weighted path length of optimum binary search trees,We derive upper and lower bounds for the weighted path length P. of optimum binary search trees. In particular, 1/log3 H≤P.≤2+H where H is the entropy of the frequency distribution. We also present an approximation algorithm which constructs nearly optimal trees.

,The complexity of negation-limited networks — A brief survey, term of order n.log.n is saved. However, for sets of lower inversion complexity, no interesting bounds are known on the amount of savings possible. Good upper bounds on the amount of such savings would enable lower bounds on combinational complexity to be concluded from lower bounds on the negation-restricted complexity.
