Super fast Fibonacci number generator for Python and Ruby

November 15th, 2008 | Category: Programming, Python, Ruby

Some time ago at work my colleagues and I were discussing the performance of various programming languages (Python, C++, C#, VBA, JavaScript, Java, VB.Net, Ruby) and which one was the fastest. I therefore started writing recursive Fibonacci methods for each language and timing their execution (anything to get out of doing real work!). This then led to looking into faster methods of generating the Fibonacci sequence. Below are three different method for generating the sequence; recursive (slow), matrix (fast), and pure maths (super fast). Though I have yet to come across a need to generate a Fibonacci number in one of my applications, I thought I would share this as it may be of interest to some of you out there.

PYTHON

Recursive (slow)

  1. import time
  2.  
  3. def fibonacci(n):
  4.     if n < 2:
  5.         return n
  6.     else:
  7.         return fibonacci(n-1) + fibonacci(n-2)  
  8.  
  9. start = time.clock()
  10. for i in range(36):
  11.     print "n=%d => %d" % (i, fibonacci(i))
  12. end = time.clock()
  13. print "Time elapsed = ", end - start, "seconds"
Recursive (slow) Fibonacci Results

Matrix (fast)

Note: This requires the python-numpy module (Ubuntu users can apt-get install python-numpy)

  1. import time
  2. import numpy
  3.  
  4. fibonacci_matrix = numpy.matrix([[1,1],[1,0]])
  5. def fibonacci(n):
  6.     return (fibonacci_matrix**(n-1)) [0,0]
  7.  
  8. start = time.clock()
  9. for i in range(36):
  10.     print "n=%d => %d" % (i, fibonacci(i))
  11. end = time.clock()
  12. print "Time elapsed = ", end - start, "seconds"
Matrix (fast) Fibonacci Results

Pure Maths (super fast)

  1. import time
  2. from math import sqrt
  3.  
  4. def fibonacci(n):
  5.     root5 = sqrt(5)
  6.     phi = 0.5 + root5/2
  7.     return int(0.5 + phi**n/root5)
  8.  
  9. start = time.clock()
  10. for i in range(36):
  11.     print "n=%d => %d" % (i, fibonacci(i))
  12. end = time.clock()
  13. print "Time elapsed = ", end - start, "seconds"

RUBY

Recursive

  1. def fibonacci(n)
  2.     if n < 2
  3.         n
  4.     else
  5.         fibonacci(n-1) + fibonacci(n-2)
  6.     end
  7. end
  8.  
  9. start_time = Time.now
  10. 36.times do |i|
  11.     puts "n=#{i} => #{fibonacci(i)}"
  12. end
  13. end_time = Time.now
  14. puts "Time elapsed = #{end_time - start_time} seconds"

Matrix

  1. require ‘matrix’
  2.  
  3. FIBONACCI_MATRIX = Matrix[[1,1],[1,0]]
  4. def fibonacci(n)
  5.         (FIBONACCI_MATRIX**(n-1)) [0,0]
  6. end
  7.  
  8. start_time = Time.now
  9. 36.times do |j|
  10.         puts "n=#{j} => #{fibonacci(j)}"
  11. end
  12. end_time = Time.now
  13. puts "Time elapsed = #{end_time - start_time} seconds"

Pure Maths

  1. def fibonacci(n)
  2.         root5 = Math.sqrt(5)
  3.         phi = 0.5 + root5/2
  4.         Integer(0.5 + phi**n/root5)
  5. end
  6.  
  7. start_time = Time.now
  8. 36.times do |j|
  9.         puts "n=#{j} => #{fibonacci(j)}"
  10. end
  11. end_time = Time.now
  12. puts "Time elapsed = #{end_time - start_time} seconds"

For anyone who wishes to run some language benchmarks themselves (if you are really bored!!), here is the recursive sequence for other languages.

PHP

  1. function fibonacci($n) {
  2.     if ($n < 2) {
  3.         return $n;
  4.     }
  5.     else {
  6.         return fibonacci($n - 1) + fibonacci($n - 2);
  7.     }
  8. }
  9.  
  10. $start_time = microtime(true);
  11. for ($i = 0; $i < 36; $i++) {
  12.     $fib = fibonacci($i);
  13.     print "n=$i => $fib\n";
  14. }
  15.  
  16. $end_time = microtime(true);
  17. $diff_seconds  = $end_time - $start_time;
  18. print "Time elapsed = $diff_seconds seconds";

VBA

  1. Private Function Fibonacci(ByVal n As Integer) As Long
  2.     If n < 2 Then
  3.         Fibonacci = n
  4.     Else
  5.         Fibonacci = Fibonacci(n - 1) + Fibonacci(n - 2)
  6.     End If
  7. End Function
  8.  
  9. Sub Main()
  10.     Dim StartTime As Date
  11.     Dim EndTime As Date
  12.  
  13.     StartTime = Time
  14.     For Index = 0 To 35
  15.         Debug.Print "n=" &amp; Index &amp; " => " &amp; Fibonacci(Index)
  16.     Next
  17.     EndTime = Time
  18.  
  19.     Debug.Print "Time elapsed = " &amp; (EndTime - StartTime) * 86400
  20. End Sub

C#

  1. static int Fibonacci(int n)
  2.     {
  3.         if (n < 2)
  4.         {
  5.             return n;
  6.         }
  7.         else
  8.         {
  9.             return Fibonacci(n - 1) + Fibonacci(n - 2);
  10.         }
  11.     }
  12.  
  13.     static void Main(string[] args)
  14.     {
  15.         Stopwatch stopwatch = new Stopwatch();
  16.         stopwatch.Start();
  17.         for (int i = 0; i < 36; i++)
  18.         {
  19.             Console.WriteLine("n={0} => {1}", i, Fibonacci(i));
  20.         }
  21.         stopwatch.Stop();
  22.         TimeSpan excecutionTime = stopwatch.Elapsed;
  23.         Console.WriteLine("Time elapsed = {0:00}.{1:00} Seconds",
  24.                 excecutionTime.Seconds, excecutionTime.Milliseconds / 10);
  25.         Console.ReadLine();
  26.     }

JAVA

  1. public static void main(String[] args) {
  2.         long start = System.currentTimeMillis( );
  3.         for (int i = 0; i < 36; i++)
  4.         {
  5.                 System.out.println("n=" + i + " => " + Fibonacci(i));
  6.         }
  7.         long end = System.currentTimeMillis( );
  8.         double deltaT = end-start;
  9.         System.out.println("Time elapsed = " + deltaT/1000 + " seconds.");
  10.         try {
  11.                 System.in.read( );
  12.         } catch (IOException e) {
  13.                 e.printStackTrace();
  14.         }
  15. }
  16.  
  17. public static int Fibonacci(int n) {
  18.         if (n < 2)
  19.         {
  20.             return n;
  21.         }
  22.         else
  23.         {

Help Required Localizing Python Version of Furius ISO Mount

November 05th, 2008 | Category: Programming, Python

Due to my Microsoft Windows .Net programming background, I have had no experience localizing Python applications. As such, I am sending out of request for a Python coder to assist me in (i.e., do :p) the required setup and coding. If you are able to localize python applications (generate PO templates and files, create correct directory structure for the .mo files, add localization coding etc) and would like to help with Furius ISO Mount, please get in touch as your help will be greatly appreciated!

Many thanks.

Automaticaly Download and Process NZB’s in Mandriva 2009 using Hellanzb

October 15th, 2008 | Category: Mandriva 2009, Python

From the Hellanzb website:

hellanzb is a Python application designed for *nix environments that retrieves nzb files and fully processes them. The goal being to make getting files from Usenet (e.g.: Giganews Newsgroups) as hands-free as possible. Once fully installed, all thats required is moving an nzb file to the queue directory. The rest; fetching, par-checking, un-raring, etc. is taken care of by hellanzb.

Installing Hellanzb

Open a terminal

Install the prerequisites (resolve dependencies as required)

su
urpmi libpython2.5-devel parchive2 unrar python-twisted

Get the latest version of hellanzb (version 0.13 latest at time of writting)

aria2c http://www.hellanzb.com/distfiles/hellanzb-0.13.tar.gz

Unpack archive

tar -xzvf hellanzb-0.13.tar.gz

Install hellanzb

cd hellanzb-0.13
python setup.py install

Configure Hellanzb

cp /usr/etc/hellanzb.conf.sample /usr/etc/hellanzb.conf
kwrite /usr/etc/hellanzb.conf

In the defineServer section changes the id, hosts, username and password values to those supplied by your usenet provider.

Under Important locations change Hellanzb.PREFIX_DIR = ‘/ext2/’ to Hellanzb.PREFIX_DIR = ‘/home/YOUR-USER-NAME/’

Other settings and locations can be changed if required but this is not necessary.

Running Hellanzb

Open a terminal

hellanzb.py

Download a NZB file and place it in

/home/YOUR-USER-NAME/nzb/daemon.queue/

Once files have been processed they will be placed in

/home/YOUR-USER-NAME/usenet/
