We can prove that there is no limit to the number of primes, but they slowly become more sparse asthey get higher in value.Eratosthenes invented a very simple and effective algorithm for finding prime numbers, based on therealization that once we find a prime number, we have found an ...
1, 2, 3, ...} need be sieved. For example, to illustrate the proportionality of this ratio, we find that 25% of the first 100 natural numbers are prime, while 72% of numbers not divisible by 2, 3, or
The concept of algorithm has existed since antiquity.Arithmeticalgorithms, such as adivision algorithm, was used by ancientBabylonian mathematiciansc. 2500 BC andEgyptian mathematiciansc. 1550 BC.[10]Greek mathematicianslater used algorithms in thesieve of Eratosthenesfor finding prime numbers,[11]and ...

So people have invested quite a lot of computation power into finding lower bounds. It turns out, for testing a 32 bit integer it is only necessary to check the first 4 prime bases: 2, 3, 5 and 7. The smallest composite number that fails this test is $3,215,031,751 = 151 \cdot...

Algorithm for finding a primitive root¶ A naive algorithm is to consider all numbers in range$[1, n-1]$. And then check if each one is a primitive root, by calculating all its power to see if they are all different. This algorithm has complexity$O(g \cdot n)$, which would be ...
Concretely, and more generally, this paper gives a framework based on quantum walks for finding any constant-sized sub-hypergraph in a 3-uniform hypergraph (Theorem 5). This is an extension of the learning-graph-based algorithm in [18] to the hypergraph case in terms of a nested quantum wa...
