Web12 jul. 2024 · 1. A sorting algorithm is able to identify any permutation of a sorted array of n elements, and there are n! such permutations. Hence, assuming that we can always choose decisions that halve the subset of possible permutations, the height of the decision tree won't exceed ⌈ log 2 n! ⌉, corresponding to a complete tree of 2 ⌈ log 2 n ... WebThe runtime complexity of a DT is the largest number of queries required to find the MST, which is just the depth of the DT. A DT for a graph G is called optimal if it has the smallest depth of all correct DTs for G.
