RE: GSoC 19: Information pertaining to 'Lagged Fibonacci Generators'

[Abhishek Dhadwal]

Dear Sir, 

I’ve added skeletal draft of my GSOC proposal (as per the Apache foundation’s 
guidelines) below :

GSOC-19 Application :- RNG-32: Implement More Generators 

Background 

The Commons RNG is focused on the utilization of Java-only implementations of 
various standard generators, with focus being placed on fast generators with 
strong uniformity and predictability. 

Design / description of work 

-  Implementation of Linear Congruential Generators 

-  Implementation of Lagged Fibonacci Generators 

-  Implementation of PCGs 

Results for the Apache community 

The implementation of PRNGs will allow for the occurrence of speed and 
regularity for sequences of pseudo random numbers, easing the creation of 
applications involving data encryption, games and gambling.   

Deliverables 

Java Implementations for the following PRNGs shall be provided: 

 1. Linear Congruential Generators : One of the oldest and best known PRNG 
algorithms, LCGs create pseudo random sequences of numbers using discontinuous 
piecewise linear equations. 

  2. Lagged Fibonacci Generators : An improvement over Linear Congruential 
Generators , these PRNGs take their inspiration from the Fibonacci series, and 
utilise the following generalised formula : 
Sn = Sn-k * Sn-j (mod m) , where ‘*’ is a binary operation. (NOTE: k and j may 
not be selected randomly) 

  3. PCGs : Permuted Congruential Generators are RNGs which are modern, light 
and reliable in nature, and are more efficient than LCGs while utilising a 
power of 2 modulus, leading to unbiased output bits. 

Scheduling 

May 27- Beginning of coding and testing for Linear Congruential Generators 

June 17 - Testing for LCG commenced along with potential bug fixing 

June 24 18:00 UTC - Testing phase 1 - complete. Mentor evaluation of LCGs begin 
/ Evaluation 1 

June 28 18:00 UTC - Phase 1 Evaluation deadline 

June 29 - Beginning of implementation for Lagged Fibonacci Generators 

July 15 - Student testing of implemented LFGs begins along with bug fixing 

July 22 18:00 UTC - Testing Phase 2 – Complete. Mentor evaluation of LFGs begin 
/ Evaluation 2 

July 26 18:00 UTC - Phase 2 Evaluation deadline 

July 27 -Design and Coding for Java Implementation of PCGs begin  

August 12 - Student testing of PCGs begins along with the implementation of 
final fixes to code  

August 19 - 26 18:00 UTC - Final phase of Student Testing Complete. Mentor 
evaluation of overall code begins / Final evaluation 

August 26 - Sept 2 18:00 UTC - Mentors submit final student evaluations 

September 3- Final results of Google Summer of Code 2019 announced 

Other commitments 
None during the period of May 27th-July 27th . College begins from July 27th, 
but shall not affect the deadlines proposed. 

Community engagement 
Interacted with Gilles sir in the JIRA forum, along with subscription and 
interaction with members of the developer’s mailing list. Project importing and 
building using Maven also performed.

   -- END OF PROPOSAL—
   
NOTE: I had created a table for the scheduling part, which got removed when I 
copied my draft proposal from the word document to mail, along with various 
cosmetic changes which I had applied to the text.
Should I add my previous experience with Java and other qualifications, along 
with sources of information? What other changes should I make to my current 
proposal ? Feedback would be highly appreciated.

PS :- Apologies for not replying earlier, I’ve been under the weather for the 
past few days. I shall undertake the changes you and Alex sir have advised, and 
reply as soon as possible.

Thanking you, 
Yours Faithfully,
Abhishek

Re: GSoC 19: Information pertaining to 'Lagged Fibonacci Generators'

[Gilles Sadowski]

Hi Abhishek.

Overall it looks good to me (but I'm not used to laying out GSoC proposals
so it might be good to have additional comments).

I've added a few remarks in the text (see below).

You should probably insert the words "random numbers" somewhere.
Perhaps add this link
https://en.wikipedia.org/wiki/Pseudorandom_number_generator
as general information about the topic.

Perhaps add web links (e.g. to the corresponding Wikipedia pages).

I'd be wary mentioning "data encryption"; it's probably a long way from
the deterministic RNG implementations, that are the scope of this
component, to a reliable cryptographic appplication.

"Simulations" is probably worth mentioning among the potential uses.
You could also mention actual applications that use RNGs (and maybe
issues that they could encounter with using a "bad" generator).

Reading one of the above links, I've just found out another generator that
looks quite easy to implement:

Honestly, I've no idea about whether this schedule is realistic.
I mean: Assuming full-time commitment, it could probably be
finished much faster. ;-)
At this point, it looks to me that the longest part will be getting
acquainted with the framework of "Commons RNG" (and even
this will probably look fairly easy once you get the hang of it).
Then the coding of the algorithm(s) will be pretty straightforward:
It seems (sometimes much) less than 20 lines of code each.
Most time will probably be spent porting from C (with its caveat
of data type adaptation), ensuring full coverage and reproducibility
of the reference implementation's output.

That is to say that we should perhaps add additional task(s)...
An obvious one would be to mention:
 - Look for more RNG algorithms, and implement them, if
   time permits.

[Rob Tompkins]

Good question. I am.  But I won’t be able to finish things up until tomorrow. 
It’s been a hectic week...couple of night shifts friend in from out of town and 
such.

[Alex Herbert]

Has this testing suite been investigated:

PractRand

http://pracrand.sourceforge.net/ 

It may provide a useful alternative to Dieharder or TestU01. I supports direct 
calls to the test suite using an API or piped data from stdin.

I didn't know about it, until coming across from the "Middle-square

Sure; it would be nice to expand the "quality" table of the userguide.
[And IIUC there are RNG implementations which we could add to
the ports list.]

RE: GSoC 19: Information pertaining to 'Lagged Fibonacci Generators'

[Abhishek Dhadwal]

Dear Sir,
Honestly, I've no idea about whether this schedule is realistic. I mean: 
Assuming full-time commitment, it could probably be finished much faster. ;-)
Oh, okay. As per your estimates, how many days should I allocate for the 
implementation and testing of each generator (inclusive of the time spent 
porting from C) ?
At this point, it looks to me that the longest part will be getting
acquainted with the framework of "Commons RNG" (and even
this will probably look fairly easy once you get the hang of it).
And how much time for this? I’ll update my timeline accordingly.
That is to say that we should perhaps add additional task(s)...An obvious one 
would be to mention:
 - Look for more RNG algorithms, and implement them, if time permits.
Alright. I’ll implement all of the changes suggested, and let you know.
Thank you so much for your input !
Regards,
Abhishek

RE: GSoC 19: Information pertaining to 'Lagged Fibonacci Generators'

[Abhishek Dhadwal]

Dear Sir,
This all looks good. I would reemphasise that you should find a reference 
implementation of any new generator so that you can run it to produce numbers 
given a known seed. This can be used to test the Java version you create 
produces exactly the same sequence.
Thank you for the feedback ! I shall keep that in mind while performing the 
aforementioned implementations.
If you look at the unit tests for each generator in commons-rng-core you will 
see the type of testing process to implement.
Will do so. Thank you again!
The changes I suggested for building on Java 11 are now in master. Just update 
and try again:

Let me know if you still get an error.
Alex
Unfortunately, even after having my repo updated to the latest version, I’m 
still getting an error. Seems like the file or path specified for a program 
known as “svm” cannot be found. The output is as follows :

To build the site you need to install svn (subversion). You don’t need the site 
unless you want to look at all the reports for the latest build. However you 
can run reports for different tools individually anyway.

Try again without site in the maven command.

mvn clean package

I'm not good at estimates. ;-)
In the end, if there is more time, there will always be something to do!

I designed the component, with the goal of fixing deficiencies[1][2]
of the "Commons Math" library and tried to provide a framework that
would be easy to use[3] (for users and contributors), but it's hard to
know how newcomers approach the result.
Alex went through this, so he can probably share his experience.

Best,
Gilles

I'm not sure about the last two points; I imagined that one would want to be
able to explicitly see the limitation of some algorithm.
A "null" seed is convention for telling the library to provide a good sequence
without much hassle, but if a user says that the seed is zero, then it might
be useful to honor that.  One should read the doc. :-)

OK. So only try and guarantee a functional provider if no seed is given and the 
seed is ‘correctly' made by the library. Let the user mess up their own seed. 
That follows from having no checks on the input seeds (beyond length) in the 
actual generators in the core module too.

I’ll do this when I have an attempt to update the ProviderBuilder code for 
building generators.

Currently I am still refining the command line program to run the stress test. 
It started as a small job that got big. I’ll create a PR for discussion and 
testing when it is done. Hopefully this week.
