Distances Between NFL Cities
This is the data I used in my paper on
Realignment in the NFL.
The following are available:
- A map of the optimal solution to the problem
of minimizing the sum of intradivisional distances with no side
constraints. Two versions available:
a small, sylized version,
or a jpeg geographically accurate picture.
- A numbered list of the cities.
- The 32x32 distance matrix of the cities.
- An MPS file of the integer programming
formulation, including some cutting planes.
This formulation returns the optimal solution to the
realignment problem.
The optimal solution uses these
48 edges and has value 27957km.
- The latitude/longitude coordinates of the cities,
expressed as degrees-minutes-seconds for latitude and then for longitude.
- To convert from latitude/longitude to distances, I used a formula
available from the
FAQ at
TSPLIB.
- Here is my fortran implementation
of the formula to translate latitude/longitude coordinates into a
distance matrix.
- The
raw data
that I used to extract the locations of the 32 NFL cities is available
as a compressed file from the University of Texas.
- Optimal solutions under various
restrictions.
- A news
release from the NFL detailing the
chosen realignment.
There are additional jpeg images available
(thanks Dina!):
