Question

Transcribed Image Text:1. Choose a vertex to start at, then travel along
the connected edge that has the smallest
weight. (If two or more edges have the same
weight, pick anyone.)
2. After arriving at the next vertex, travel
along the edge of the smallest weight that
connects to a vertex not yet visited. Continue
this process until you have visited all vertices.
3. Return to the starting vertex.
1. Vincent needs to visit the pet store,
the shopping mall, the local farmers
market, and the pharmacy. His
estimated driving times (in minutes)
between locations are given in the
table. a) Use the greedy algorithm
to find two possible routes, starting
and ending at home, that will help
Vincent minimize his total travel time.
(You need to find two answers for
this problem.) Draw the weighted
graph that represents each route
(trace the route) and compute for the
total travel time.
