Explanation of Solution

Given Information:

The shortest closed tour of the graph with length approximately is 24.89. The directed acyclic graph is shown below-

Introduction to Algorithms, Chapter 15, Problem 1P , additional homework tip 1

Explanation:

The dynamic-approach used to find the longest length simple path consider the graph G and vertices as V. The longest simple path must go through some edge of weight s or t . The algorithms to compute the longest weight path is longest(G,s,t)=1+max(longest(G,s',t)) .

The base condition for the algorithm is s=t and the initial length is 0.It can see that it consider this many possible sub-problems by taking |G| and complete graph on vertices V .

The algorithm to compute longest simple path in a directed acyclic graph is given below-

LONG-PATH(G,u,s,t,len)

If t==s then

set len(s)=0 .

return ( len,u )

else if u[s]==NULL then

Return (len,u).

else

for each adjacent vertex u∈G of s.

Check the distance after adding new vertex i.

if w(s,u)+len[u]≥len[s] then

len[s]=w(s,u)+len[u] .

u[s]=t .

end if.

end for.

end if.

return ( len,u ).

end.

In above algorithm, loop of for is used to determine the longest path and the longest path visit all vertex by checking all adjacent vertex.

The time taken by the algorithm is depends upon the number of vertex visited and the number of edges in the longest simple path. Suppose V represent the number of vertex used in the computing the longest simple path and E represent the number of edges then total running time of the algorithm is equals to O(V+E) .

The player starts at the bottom left corner of the labyrinth. He has to get to the top right corner of the labyrinth as fast he can, avoiding a meeting with the evil dragon. The player can move only in four directions: left, right, up or down. There are several escape paths in all labyrinths. The player’s character should be able to moved with the well known WASD keyboard buttons. If the dragon gets to a neighboring field of the player, then the player dies. Because it is dark in the labyrinth, the player can see only the neighboring fields at a distance of 3 units.
