The authors use a fast, efficient method to construct the candidate set of feasible restoration plans satisfying the voltage and current constraints of the distribution system and evaluate them based on the following criteria: number of switching, amount of live load transfer and contingency preparedness by applying fixed position ordered tree technique.

A representation for compact layout of logistics facilities based on an O-tree(ordered tree) was proposed following the approach for design of very large integrated circuit.

Based on ordered tree, an algorithm for reading order detection after page top-down decomposition for constructing layout objects .

<Abstrcat> To efficiently mine all frequent pattern trees from the semi-structured web data,the semi-structured data were modeled as labeled-ordered tree and an algorithm for mining all frequent pattern trees in an ordered data tree was proposed.

To increase the efficiency of sequential combination tree method,it is necessary to make full use of information in the constraint conditions.

Due to its complicated computation,a solution with solution space decomposition,limitation and sequential combination tree method is proposed,based on the characteristics of the objective function and consistence of the restrictions.

An Image Encoding Algorithm of Ordered Quad-tree in High Frequency Subbands;

Namely the lowest frequency subband is encoded separately,the ordered quad-tree is defined in high frequency subbands so that the important wavelet coefficients are transmitted by priority,and the run-length is applied.
