Subject Re: apply simplex method to fix linear programming in spark
Date Sun, 01 Nov 2015 17:49:04 GMT
Hi Ted Yu,
Thanks very much for your kind reply.Do you just mean that in spark there is no specific package
for simplex method?
Then I may try to fix it by myself, do not decide whether it is convenient to finish by spark,
before finally fix it.
Thank you,Zhiliang

 A brief search in code base shows the following:
    TODO: Add simplex constraints to allow alpha in (0,1)../mllib/src/main/scala/org/apache/spark/mllib/clustering/LDA.scala
I guess the answer to your question is no.

Dear All,
As I am facing some typical linear programming issue, and I know simplex method is specific
in solving LP question, I am very sorry that whether there is already some mature package
in spark about simplex method...
Thank you very much~Best Wishes!Zhiliang
