June 2008 - Traveling Spaceman Problem

Below is a three-dimensional map of the universe containing eight galaxies that you, as the traveling spaceman, wish to visit. Each galaxy's position in the universe is indicated by the accompanying table.


Galaxy     x     y     z
a     26     38     30
b     75     6     55
c     3     46     66
d     73     59     75
e     37     72     7
f     42     83     67
g     21     77     91
h     80     18     4


Questions:
1. Starting (and ending) at galaxy 'a,' in what order should you visit each galaxy to minimize the traveled distance? You must visit each galaxy and you cannot visit any galaxy more than once.
2. What is the total distance traveled
