4 cards from this section. Quick, good the night before a test.
What is the time complexity of the naive solution to the closest pair problem?
Think about how many pairs of points are being compared.
Why is it beneficial to sort points in a divide and conquer algorithm?
How does sorting impact distance checks?
What algorithm does the section focus on for finding the closest pair of points?
Recall the significant efficiency variances among algorithm types.
Which of the following is true regarding the time complexity of the closest pair algorithm discussed?
Think about the covered algorithm phases and their efficiencies.
You are given a set of n points distributed randomly on a 2D plane. Describe how you would handle data cleaning before applying the algorithm.
Consider the implications of point clustering.
Analyze the worst-case scenario for the divide and conquer algorithm. How does this contrast its typical performance?
