I came across this Algorithm and was wondering what exactly it is, how it's called and what to use it on...

The code (Python) is this:

def unknown(n):
    n = abs(n)
    a = 0
    t = 2
    while t <= n:
        if n % t == 0:
            a += 1
            n /= t
        else:
            t += 1
    return a

here some results:

0 -> 0
1 -> 0
2 -> 1
3 -> 1
4 -> 2
5 -> 1
6 -> 2
7 -> 1
8 -> 3
9 -> 2
10 -> 2
11 -> 1
12 -> 3
13 -> 1
14 -> 2
15 -> 2
16 -> 4
17 -> 1
18 -> 3
19 -> 1
20 -> 3
30 -> 3
101 -> 1

It brute-force counts the number of prime factors of n, each counted according to its multiplicity.

t is the current factor being tested and n % t == 0 only if n is an integer multiple of t. If it's divisible, n is divided and the division is tried again (to account for the multiplicity of that factor); otherwise, the next integer is tried, up to (the original) n. Even if the division by non-primes is tried, it doesn't skew the result because all the lower primes have already been tried, so they won't ever succeed.

An obvious optimization would be to compute and memoize the primes up to the number through an efficient algorithm, and just try them.

What is an algorithm? An explainer., What can you do with these algorithms? So many things! They're used these days for a host of purposes, such as automating stock market  What is Algorithm. An algorithm is set of instructions for solving a problem or accomplishing a task. One common example of an algorithm is a recipe, which consists of specific instructions for preparing a dish/meal. Every computerized device uses algorithms to perform its functions.


It's computing the number of prime factors of n. Notice that any prime returns 1.

Artificial Intelligence: How Algorithms Make Systems Smart, Algorithms are used for calculation, data processing, and automated reasoning.” Whether But more surprising is their widespread use in our everyday lives. Algorithms are always unambiguous and are used as specifications for performing calculations, data processing, automated reasoning, and other tasks. As an effective method, an algorithm can be expressed within a finite amount of space and time, and in a well-defined formal language for calculating a function.


It's the sequence

Number of prime powers (not including 1) that divide n

What is an algorithm and why should you care? (video), Learn the concept of recursion, a technique that is often used in algorithms. See how to use recursion to calculate factorial and powers of a number, plus to  An algorithm is a finite list of instructions, most often used in solving problems or performing tasks. You may have heard the term used in some fancy context about a genius using an algorithm to do something highly complex, usually in programming.


The prime factors of a number n is being calculated

for example 1= 1×1 =0 since 1 is neither prime nor composite

2 = 2×1 => 1

3 = 1×3 => 1

4 = 2×2 => 2

5 = 1×5 => 1

6 = 1×2×3 => 2

7 = 1×7 => 1

8= 2×2×2 => 3

Algorithms | Computer science | Computing, That's where computer algorithms come in. The algorithm is the basic technique used to get the job done. Let's follow an example to help get an understanding  Algorithm definition is - a procedure for solving a mathematical problem (as of finding the greatest common divisor) in a finite number of steps that frequently involves repetition of an operation; broadly : a step-by-step procedure for solving a problem or accomplishing some end.


What is an Algorithm? - Definition & Examples, In its purest sense, an algorithm is a mathematical process to solve a are also depth, breadth and first searches used by web applications;  All of Computer Science is about algorithms and problem solving. From an on-line dictionary: a process or set of rules to be followed in calculations or other problem-solving operations, especially by a computer.


What is a "computer algorithm"?, You use code to tell a computer what to do. Before you write code you need an algorithm. An algorithm is a list of steps to follow in order to solve a problem. That's where computer algorithms come in. The algorithm is the basic technique used to get the job done. The algorithm is the basic technique used to get the job done. Let's follow an example to help get an understanding of the algorithm concept.


What is algorithm?, A brief history of the Facebook algorithm. 2004 – 2009: Facebook was born in 2004, but its newsfeed didn’t show up until 2006. The Like button premiered in 2007, but it’s probably safe to say that Facebook didn’t have what we think of as “the algorithm” until 2009, when the platform debuted a new sorting order for newsfeeds based on each post’s popularity.
