Problem SSLP points
For this problem, we'll modify Dijktra's to compute the longest paths from a source vertex to all
other vertices in a weighted, directed, acyclic graph. Note that this is a hard problem for a general
graph. But doable for a DAG!
a For the graph above, give a valid topological sort of the vertices.
Solution:
b Give pseudocode for an algorithm to compute the longest paths on a DAG like the one above.
Your algorithm should take a graph represented in an adjacency list, a source vertex and
a weight function and you can assume that the vertices are topologically sorted. Hint: You
can callmodify any helper functions we've seen in class.
Solution:
c Give the final and values your algorithm would generate for the graph above.
