Hi everyone, it’s Alex and Lindsay here writing the blog
post for today! Today we explored
Hollywood Studios, so to start off this blog we have a picture of the whole
group at the entrance to the park (if you haven’t noticed, group pictures at
the entrance to the parks has been a bit of a theme here).

Knapsack Competition
In yesterday’s blog, Caroline and Jamie mentioned an
assignment we were given involving the classic Knapsack Problem. In this problem you have a set amount of
space (think a set amount of space in your suitcase or knapsack) that you are
trying to fit items in. You value some
items more than others (for example, you might rather pack your toothbrush than
your antique teacup set for your trip to Disney). The value placed on each item is called
utility, which is what we are trying to maximize in the Knapsack Problem.
The assignment we received yesterday was a variation of the
Knapsack Problem. Students were split into four groups of three (plus a group
of the three professors) to engage in some friendly math-related competition. The
goal of this assignment was to fit certain rides in Hollywood Studios into a
fixed amount of time to get the most utility points. Each group had from 9 am,
when Hollywood Studios opened its gates until 11:20, when we had lunch
reservations. Each ride was assigned a certain utility value (meaning riding
one ride could be more beneficial than riding another ride with a lower
utility) so the goal was to get the highest total number of utility points by
riding the most (and most valuable) rides. Yesterday we were all given data
about the rides’ average wait times, lengths of the rides, and distances from
the other rides so that groups could plan a schedule.
This morning we had the opportunity to actually test our
plans. All 15 of us arrived at Hollywood
Studios half an hour before the park opened at 9 am. We got to see how Disney dealt with all of
the people crowded by the entrance gates waiting for the park to open. Just before nine, they let everyone part of
the way into the park. It was really
exciting being at the front of the crowd waiting to get on the first rides, and
the competition with the other students (and professors!) made it even more exciting.

Once the Disney cast members released the crowds into the
park, our groups started to take different paths. My group (Lindsay) went straight for the Rock
n Roller Coaster, because the night before we had worked out that it had the
highest utility compared to the time we would spend waiting in line and riding
the ride. We ended up riding the ride
five times, and by the last time we had the ride pretty much memorized. We squeezed in one last short ride at the end
(Star Tours) before heading to lunch.
My group (Alex) worked out a strategy the night before where we made a schedule for the time period through a trial and error method, using different starting points and different pathways. In the end, we ended up hitting Tower of Terror twice, Rock 'n' Roller Coaster twice, and then other rides with lower utility. It's safe to say we really enjoyed doing this assignment!
Did I Hear a 3-Course Meal?

Group at Mama Melrose's |
Drumroll… In third place we had a tie between three of the groups (both of us, Lindsay and Alex, were in this category…). In second place were Zack, Courtney, Alyssa. The winners of the competition were…. the professors! We won’t deny that their Ph.D.’s in math might not have hurt their chances in the competition.
Time to Explore!
