Euclidean shortest path

Imagine you have a toy car and you want to move it from one point to another point on a map with many roads crisscrossing each other. You want to take the shortest path to get there.

The Euclidean shortest path is one way to find the shortest path between two points on a map. It means the path that has the shortest distance between the two points.

Think of the map as a big piece of paper, and the two points as two dots on the paper. The Euclidean shortest path is like a straight line that connects those two dots.

However, in real life, we can't always walk or drive in a straight line from one point to another. There might be buildings or other obstacles that make us go around. And we might not always know of the shortest path that goes around those obstacles, so finding the Euclidean shortest path might not be possible.

In summary, the Euclidean shortest path is like drawing a straight line between two points on a map, but real-life situations might make it impossible for us to follow that line directly.
