Well, imagine you're in a candy shop with your friend, and there are only two types of candy - lollipops and gummy bears. You both love both types of candy, but you can only buy one type each.
Now, let's say that the shop sells more lollipops than gummy bears, and your friend really wants a lollipop. You, on the other hand, don't really care which candy you get as long as you get something. So you decide to buy a gummy bear since you know your friend really wants a lollipop.
This decision you made based on what your friend wanted is similar to the idea of Wardrop equilibrium. It's a concept used in game theory to explain how people make choices when there are limited resources or options available.
In this case, you and your friend were both trying to maximize your happiness (or utility, as it's called in economics) by choosing the candy you wanted the most. However, because there were limited resources (only one type of candy each), you had to make a decision based on what would make both of you the happiest overall.
Wardrop equilibrium is the idea that everyone involved in a situation will make the best decision for themselves, given what they know about the situation and the decisions made by others. It's a kind of balance or equilibrium that's reached when everyone is making the best decision for themselves, given what they know.
So in short, when there are limited resources or options, Wardrop equilibrium is the idea that everyone will try to make the best decision for themselves while also considering what others are doing, in order to reach a kind of balance where everyone is as happy as possible.
