Subject Re: [math] FW: [interest in] SummerOfCode2005 "commons-math" project
Date Tue, 14 Jun 2005 05:38:49 GMT
Hi!

I spent some days exemining existing Math package, MathWishList and
commons-dev Mailing List. Afterall, I want to represent at your disposal the
project I am going to apply in the Summer Of Code 2005.

PROJECT TITLE: Alternative Random Number Generators Implementation For
Jakata Commons Math

SYNOPSIS:
Generation of completely unpredictable random numbers is impossible. But
there is a wide range of good-working algorithms which allow to achieve more
or less "randomness". In the "Jakarta-commons Wiki MathWishList" there is a
request for implementing alternative pseudo-random number generators (PRNG)
<http://wiki.apache.org/jakarta-commons/MathWishList>. Considering this
request I chose this project for the "Google SummerOfCode 2005".

DELIVERABLES:
During the phase of the project I am going to implement next algorithms:
I. Uniform Deviates PRNG:
1) "Minimal" random number generator of Park and Miller with Bays-Durham
shuffle
2) Long period random number generator of L'Ecuyer with Bays-Durham shuffle
3) Knuth's subtractive Random Number Generation algorithm
II. Binomial Distribution PRNG.

PROJECT DESCRIPTION:
As for the background for the project I chose the resourse "Numerical
Recipes: The Art Of Scientific Computing" and the book of Knuth's "The Art
of Programming".
I put before myself a goal to write:
 -- efficient
 -- fully documented
algorithms.
All the code will be written according to the "Code Conventions for the Java
Programming Language" and documented with full javadoc included.
In this project my logo is: "To make GOOD rathen that to make MUCH".

PROJECT SCHEDULE:
I hope the algorithms I will implement will be included to the Jakarta
Commons-Math subpackage Random. To achieve this goal I divide the project
time into two periods:
1. Writing the code - lasting a month, but not more than August,3
2. Updating with the proposals from the Commons-Math Mailing List - lasting
a month, but not more than September,1.

Please, let me know what do you think about my project.

Thanks,
Rostyslav.
