We obtain a 4τ approximation and also show that for some . > 0 it is NP-hard to obtain a (1 + .) approximation. Our upper bound improves upon the earlier known ratio of (3../2/+./2)[.] for all values of . > 7/3.

General Multiprocessor Task Scheduling: Approximate Solutions in Linear Time,approximation scheme that computes an approximate solution of any fixed accuracy in linear time. In terms of the running time, this linear complexity bound gives a substantial improvement of the best previously known polynomial bound [.].

On an Optimal Split Tree Problem,atio. We construct an example for which this algorithm achieves .. approximation ratio. We show that if all weights are equal and the optimal split tree is of depth O(log n), then the greedy algorithm guarantees .. approximation ratio. We also extend our approximation algorithm to the construction of a search tree for partially ordered sets.

The data structures can be used to solve a variety of problems with optimal bounds on time and extra storage. These include stacks, queues, randomized queues, priority queues, and deques.
