Good News: Performance improvement.  
Bad News: Memory leak problem still exists.

rmmseg version 0.1.2  
by pluskid  
[http://rmmseg.rubyforge.org](http://rmmseg.rubyforge.org)

== DESCRIPTION

RMMSeg is an implementation of MMSEG Chinese word segmentation  
algorithm. It is based on two variants of maximum matching  
algorithms. Two algorithms are available for using:

- simple algorithm that uses only forward maximum matching.
- complex algorithm that uses three-word chunk maximum matching and 3  
aditonal rules to solve ambiguities.

For more information about the algorithm, please refer to the  
following essays:

== CHANGES

- Add cache to find\_match\_words: performance improved.
- Implement Chunk as a module instead of a class: performance improved.
- Don’t store unnecessary data in dictionary: memory usage reduced.
