What are optimize across all these dimensions?

Optimizing across all these dimensions means making something as good as it can be in many different ways at once.

Imagine you're building a toy car. You want it to go fast, not break easily, and look cool. Each of those goals is like a dimension, they’re all important, but they might not always agree with each other. If you make the car super light so it can go faster, maybe it breaks more easily. But if you want it to look cool, you might add some extra parts that slow it down.

So, when you optimize across all these dimensions, you're like a smart builder who finds the perfect balance, making sure your toy car goes fast, stays strong, and still looks awesome. It’s not just about one thing; it's about getting everything to work together well.

Think of each dimension as a different flavor of ice cream. You want to pick the best combination, maybe chocolate for taste, vanilla for texture, and sprinkles for fun. If you only choose one flavor, you might miss out on something special. But by choosing all three, you get a treat that's even better than just one!
