Which of the below formula represent the Euclidean metric distance?




Correct answer

If we choose the Euclidean distance measure, what will the optimal solution be?
Euclidean distance measure will result in a single point optimal solution
Metropolitan metric distance will result in a range for the optimal solution
Both Euclidean distance measure will result in a single point optimal solution &Metropolitan metric distance will result in a range for the optimal solution are wrong
Both Euclidean distance measure will result in a single point optimal solution &Metropolitan metric distance will result in a range for the optimal solution are correct
