Objectives and Topics
This paper explores computational approaches to verifying Goldbach's Conjecture, an unproven mathematical concept suggesting that every even integer greater than or equal to eight can be expressed as the sum of two prime numbers. The primary research focus is the development and optimization of efficient algorithms that generate prime combinations to validate this conjecture for increasingly larger integer values.
- Theoretical overview of Goldbach's Conjecture and mathematical requirements for prime summation.
- Development of algorithmic methods to generate prime sets using the Sieve of Eratosthenes.
- Computational efficiency analysis of different verification algorithms and their time complexity.
- Practical C++ implementation strategies for prime pair verification and memory management.
Excerpt from the Book
Verification Algorithm
Consider the integer n and a set Sn consisting of all primes less than or equal to n. One can generate all such primes using a sieve such as the Sieve of Eratosthenes in O(nloglogn) time [1]. From this set of primes, we do not consider integers 0, 1, or 2 from the results and for the purpose of this article such numbers are not part of the prime set Sn. For example, given n=12, we would have Sn = {3, 5, 7, 11}.
Given Sn one can generate the combination of all pairs of primes possible. That is, one can compute n choose k where k = 2 for all primes in the set. Such an algorithm would be order O(n!/(k!(n-k)!)). With Sn stored in memory as variable v_primes of type std::vector
