Closest-point problems simplified on the RAM

By Timothy M. Chan (SODA 2002)

Basic proximity problems for low-dimensional point sets, such as closest pair and approximate nearest neighbor, have been studied extensively in the computational geometry literature. Generally, optimal algorithms designed for worst-case input require hierarchical spatial structures with sophisticated balancing conditions. But sometimes much simpler algorithms with the same performance are possible using standard, though nonalgebraic, RAM operations.
