Multiobjective optimization

So you know how sometimes you have to make a lot of decisions at once and they are all really important? Well, imagine you have a computer program that can help you make those decisions. This computer program is called multiobjective optimization.

First, let's break down what "multiobjective" means. "Multi" means many, and "objective" means goal or something you want to achieve. So multiobjective means you have many goals that you want to achieve all at the same time.

Now, let's think about how the computer program works. It looks at all your goals and tries to come up with the best way to achieve all of them at once. This is called optimization because it is trying to find the most optimal (or best) way to achieve all of your goals.

For example, let's say you are building a robot. You want the robot to be strong, fast, and able to carry heavy things. These are your three goals (or objectives). The multiobjective optimization program will look at all the different ways you could build the robot to make it strong, fast, and able to carry heavy things. Then it will try to find the best way to do all three.

The program is like a magic genie that can help you achieve all your goals at once. It's really helpful because sometimes when you try to achieve one goal, it can work against another goal. But the computer program can figure out how to do everything in a way that works together.

Overall, multiobjective optimization is a really cool tool that helps you achieve many goals at once by finding the most optimal way to do it.
