Binary search is a method that allows for quicker search of something by splitting the search interval into two. Its most common application is searching values in sorted arrays, however the splitting idea is crucial in many other typical tasks.Search...
Binary Search Algorithm is one of the widely used searching techniques. It can be used to sort arrays. This searching technique follows the divide and conquer strategy. The search space always reduces to half in every iteration. Binary Search Algorithm is a very efficient technique for searching ...
也称折半搜索算法(half-interval search algorithm)、对数搜索算法(logarithmic search algorithm) 是一种有序数组中查找特定元素的搜索算法。 搜索过程从数组的中间元素开始,如果中间元素正好是要查找的元素,则搜索过程结束。 如果某一特定元素大于或小于中间元素,则在数组大于或小于中间元素的那一半中查找,而且跟开始一样...
Since then, diverse research investigations are performed with a wide variety of multi-key search algorithms. In this paper, a new algorithm for tiered binary search is proposed. The algorithm performs multiple element binary search through tiered key search strategy that optimizes the search space ...
