the previous video was an algorithm for instantiating that covering an object with balls of radius epsilon ____ and the basic algorithm involved putting a grid over the object that you're trying to calculate the dimension of and then building some computer data structure that keeps track of each of those boxes and then walking through the trajectory point by point, looking to see which box each point lands in and then doing whatever you need to do with your data structure to keep track of how many of those boxes got ticked of that's the __(beta(??)) epsilon in the capacity dimension
