Subject [jira] Updated: (MAHOUT-102) Use Watchmaker 0.5.0 instead of 0.4.3
Date Fri, 16 Jan 2009 09:32:00 GMT


Deneche A. Hakim updated MAHOUT-102:

    Status: Patch Available  (was: Open)

The code has been updated to use the latest version of Watchmaker (0.5.0). The most important
change is the deletion of STEvolutionEngine (now we use SequentialEvolutionEngine available
with Watchmaker).

I cannot make the path delete some files, so the following changes must be done when this
patch is commited:
* remove "watchmaker-framework-0.4.3.jar" and "watchmaker-swing-0.4.3.jar" from core/lib
* add "watchmaker-framework-0.5.0.jar" and "watchmaker-swing-0.5.0.jar" (available in the
attached zip file) in core/lib
* delete "wdbc" directory and "wdbc.infos" from core/src/test/resource

>            Priority: Minor
>             Fix For: 0.1
> Watchmaker 0.5.0 is available.
> The biggest change is the availability of the SequentialEvolutionEngine, so we no more
need our own implementation of a Single Threaded Evolution Engine (STEvolutionEngine).
> There also other small changes that affect our own code, and should be updated.
