ELI5: Explain Like I'm 5

Harmony search

Okay kiddo, let me explain Harmony Search to you in a way that you can easily understand.

You know how when you are singing with your friends in class or at home, you try to match your voice with theirs? That is called harmony. Harmony Search (HS) is a type of computer algorithm that tries to find the best solution to a problem by mimicking how we humans match our voices to make beautiful music together.

Just like how you and your friends might adjust your singing pitch to fit together, HS uses a process called improvisation to change and adjust the solution until it fits the problem it's trying to solve. HS starts with an initial random solution, and then makes changes (improvisation) to it until it finds a better solution.

In the same way that you and your friends might try different melodies to match your voices, HS tries different combinations of variables and parameters to find the best solution. These variables and parameters are like the different notes that make up a melody.

HS also has something called a harmony memory, which is like a list of the best solutions it has found so far. It remembers these solutions and uses them to improve future solutions. That's like you remembering the best harmony you and your friends made so you can make an even better one in the future.

Overall, Harmony Search is a clever computer algorithm that uses the idea of harmony to find the best solution to a problem. It's a lot like how you and your friends use your voices to create beautiful music together. Cool, huh?
