Non-adaptive Algorithm
n Adaptive Algorithm: essentially breadth-first
search, nodes re-visited multiple times with
different thresholds
n Non-adaptive algorithm: recursive, assumes that
threshold is set once, n times faster than Adaptive
Algorithm (i.e., O(e))
n Applied to same example: migrate nodes 1, 2, 6, 3,
for a benefit of 518 (i.e., less optimal)
