3 cards from this section. Quick, good the night before a test.
Define the closest pair problem.
Think about what it means to measure distance.
What is the time complexity of the brute-force method?
Recall how many combinations are formed by pairs.
What is the main goal of the closest pair problem?
Focus on 'closest' versus 'farthest'.
True or False: The brute-force method is optimal for large datasets.
Consider the nature of computational efficiency.
Given a set of coordinates representing satellite locations, outline the plan using the divide and conquer method to determine the closest pair relevant for communication.
Think about how you would manage satellite data in two-dimensional space.
Describe how the closest pair algorithm adapts when points can have equal x or y coordinates.
Consider how distance definitions change with duplicate points.
