The thing is, while I have 77 pictures of my favorite roller coaster, Expedition Everest at Disney’s Animal Kingdom, and 70 of The Tower of Terror at Hollywood Studios, I only have 2 of the Flame Tree Restaurant at Animal Kingdom and many other things that aren’t as exciting to post about. If I randomly choose attractions using a non-weighted random number generator, it would be just as likely to get the lesser items as the same frequency as the greater items. Hence, I want my popular items to come up most frequently, but every once in a while, I want to be surprised by something different.
This is where I needed to build a weighted randomized value.
Read on to see how Louis implements this.
