Why is the average of comparisons of k-ary search is k* ln(N) / ln(k)? ... If this formula is correct, then ternary search will be the fastest search as k/ln(k) will be minimum (for integers) because 3 is the closest integer to "e" (the real minimum) which is very easy to prove using differentiation. ...

sequential, binary and k-ary search algorithms on a modern processor. In this context, we consider hardware-sensitive optimization strategies as well as algorithmic variations re-sulting in an eight-dimensional evaluation space. As a result, we give insights on expected interactions be-tween search algorithms and optimizations on modern hard-ware.

5.4. The Binary Search¶. It is possible to take greater advantage of the ordered list if we are clever with our comparisons. In the sequential search, when we compare against the first item, there are at most $$n-1$$ more items to look through if the first item is not what we are looking for. Instead of searching the list in sequence, a binary search will start by examining the middle item.

In computer science, tree traversal (also known as tree search) is a form of graph traversal and refers to the process of visiting (checking and/or updating) each node in a tree data structure, exactly once.Such traversals are classified by the order in which the nodes are visited. The following algorithms are described for a binary tree, but they may be generalized to other trees as well.

Ternary search, like binary search, is a divide-and-conquer algorithm. It is mandatory for the array (in which you will search for an element) to be sorted before you begin the search. In this search, after each iteration it neglects $$⅓$$ part of the array and repeats the …

A random m-ary seach tree is constructed from a random permutation of 1,…, n.A law of large numbers is obtained for the height H n of these trees by applying the theory of branching random walks. in particular, it is shown that H n /log n γ in probability as n ∞ where γ = γ(m) is a constant depending upon m only. Interestingly, as m ∞, γ(m) is asymptotic to 1/log m, the coefficient ...

If you apply binary search, you have $$\log_2(n)+O(1)$$ many comparisons. If you apply ternary search, you have $$2 \cdot \log_3(n) + O(1)$$ many comparisons, as in each step, you need to perform 2 comparisons to cut the search space into three parts.
