Use the critical path algorithm to create a priority list for the digraph below.
T4 (5)
Т6 (11)
T1 (8)
End
T2 (10)
T5 (6)
T7 (7)
ТЗ (12)
Priority list:
Give the priority as a list of task numbers. For example, you'd enter something like: 1,2,3,4,5,6,7,8,9,10
Please provide an easy way to solve it correctly.
3. Use the training data of Gauss2 example (Gauss2.train).
(a). Run the K-means algorithm with K
=
2 clusters and make a plot identifying the
clusters. Also label the points with their known classes.
= 2 clusters and make
(b). Multiple all the x1 by 10. Run the K-means algorithm with K
a plot identifying the clusters. Also label the points with their known classes.
(c). Compare the class and cluster groupings for both plots in (a) and (b). Explain any
differences between them.
(d). Use agglomerative hierarchical clustering (hclust in the MASS library) to cluster the
data, and divide them into 2 groups. You can use the function cutree to divide the
clusters into 2 groups. Report on how the predicted cluster labels compare with actual
cluster labels for each of the three methods for measuring distance between clusters,
i.e. single linkage, complete linkage and average linkage.

Represent the tournament as a graph, in which each vertex corresponds to a player and an edge joins two vertices if the corresponding players will compete against each other in a match. Next, color the edges, where each different color corresponds to a different day of the tournament. Because one player will not be in more than one match per day, no two edges of the same color can meet at the same vertex.
