See inline. The code for the deprecated algos has already been purged from 
trunk, its only the Wiki that needs cleaning up.

Subject: Re: Deprecated or drafts only algorithms what is the reasoning?
 
It could be because:-

a) they have been replaced by better performant alternatives
b) lack of usage 
c) lack of support

Please delete from wiki all algorithms that have been marked deprecated (the 
code for most of them has already been removed from trunk).

Hi all, 



I'm going through the algorithms and I noticed some are "Deprecated or
drafts only" . What is the reason?



Is it because they are less efficient compared to the supported ones or is
it due to lack of resources working on them to be supported with Mahout?



Thanks
