ELI5: Explain Like I'm 5

Direct multiple shooting method

Okay kiddo, have you ever played darts before? You throw a dart to hit a spot on a board, right? Well, imagine we have a math problem where we need to find the best way to throw the dart to hit a certain spot on the board. But instead of a dart board, we have a function, which is like a machine that takes in a number and gives us an output.

Now, one way we could try to solve this math problem is by guessing how to throw the dart and checking if we hit the spot. Then we adjust our guess and try again. This is called a trial and error method, and it takes a long time.

But there's another way! It's called the direct multiple shooting method. It's like breaking the math problem into smaller problems, like breaking a big puzzle into smaller pieces that are easier to solve. We imagine that we're throwing not just one dart, but many darts at different places on the board that eventually lead us to the spot we want to hit.

So we start by throwing a dart at the first spot and see where it lands. Then we use the output of that spot as the input for the next spot, where we throw another dart, and so on. Each time we throw a dart and hit the spot, we get closer to the final destination.

We keep doing this until we hit the spot we want. And then we use all the darts we threw along the way to come up with the best way to throw the dart and hit the spot where we want it to. It's like putting all the puzzle pieces back together to see the whole picture.

That's the direct multiple shooting method, kiddo! It's a way to solve math problems by breaking them down into smaller pieces and solving them one by one.
