Is it worth the time to run Euler solutions?
The style of using generators/ filters/ itertools can be considered about halfway between Java’s imperative style and {Haskell or Mathematica}’s functional style. Unfortunately due to Python’s slow performance on arrays and machine-word-sized integer values, many solutions are not worth the time to run it compared to the Java implementations.
What kind of program do I use to solve my problems?
Almost all my solved problems also include a Python program (except for a few). Many problems additionally have a Mathematica and Haskell program. Numerous solutions contain a detailed mathematical proof to justify why the implemented algorithm is correct.
What is problem 23 of Project Euler about?
Problem 23 of Project Euler is about factorisation of a number once again, and has a rather long description. So let me give that to you right away A perfect number is a number for which the sum of its proper divisors is exactly equal to the number.
Which is a perfect number in Project Euler?
Problem 23 of Project Euler is about factorisation of a number once again, and has a rather long description. A perfect number is a number for which the sum of its proper divisors is exactly equal to the number. For example, the sum of the proper divisors of 28 would be 1 + 2 + 4 + 7 + 14 = 28, which means that 28 is a perfect number.
Are there any Haskell solutions that depend on Java?
Many Haskell solutions depend on my shared math library module: EulerLib.hs. Some solution code contains a detailed mathematical proof of correctness. For every problem that I solved, I have a Java solution for it (and possibly code in other languages as well).
Are there any custom algorithms that can be implemented in Haskell?
Custom data structures like graphs are difficult to express cleanly in Mathematica. Custom algorithms like the sieve of Eratosthenes, especially ones most naturally expressed in terms of imperative state updates, are difficult to implement correctly or efficiently in Haskell.
How did my relationship with Project Euler start?
Mathematics is addictive and beautiful and my relationship with project euler started as interview preparation but then kept growing.
Why was Project Euler named after a mathematician?
Project Euler isn’t named after one of the greatest mathematicians of all time for nothing. While PE is about coding, it’s no less about maths. Many of the problems on the site can be solved much easier by exploiting particular mathematical properties.
