چکیده

We show how to build an alphabetic minimax tree for a sequence W = w1, . . . , wn of real weights in O(nd log logn) time, where d is the number of distinct integers ⌈wi⌉. We apply this algorithm to building an alphabetic prefix code given a sample.

Alphabetic Minimax Trees in Linear Time

We develop a linear time algorithm algorithm for the following problem: given an ordered sequence of n real weights w1, w2, . . . , wn, construct a binary tree on n leaves labeled with those weights when read from left to right so that the maximum value of wi plus depth of the i-th leftmost leaf is minimized. This improves the previously known O(n logn) time solutions [2,11,13]. We also give a ...

Minimax Trees in Linear Time with Applications

A minimax tree is similar to a Huffman tree except that, instead of minimizing the weighted average of the leaves’ depths, it minimizes the maximum of any leaf’s weight plus its depth. Golumbic (1976) introduced minimax trees and gave a Huffman-like, O(n log n)-time algorithm for building them. Drmota and Szpankowski (2002) gave another O(n log n)-time algorithm, which takes linear time when th...

Optimal Alphabetic Ternary Trees

We give a new algorithm to construct optimal alphabetic ternary trees, where every internal node has at most three children. This algorithm generalizes the classic Hu-Tucker algorithm, though the overall computational complexity has yet to be determined.

Routing plays an important role in determining the total circuit area and circuit performance and hence must be addressed as early as possible during the design process In this paper an e ective routing driven approach for technology dependent logic synthesis which relies on alphabetic tree construction is presented Alphabetic trees are trees which are generated under the restriction that the i...
