4/22/2017 · The binary search algorithm is one of the most famous search algorithms in computer science. It allows you to search a value in logarithmic time i.e. O(logN), which makes it ideal to search a number in a huge list.For example, in order to search a number in a list of 1 million number will take around 210 comparisons compared to 1 million comparison required by the linear search algorithm.

If numberToFind > array[mid] then the lower bound should be set to mid + 1 as the value at array[mid] does not match. In the opposite case the upper bound should be set to mid - 1.If you don't do so, you might get stuck in an endless recursion. Say you are looking for 12 (at index 6) and you have indexMin = 5 and indexMax = 6.mid becomes 5.Now calling

If the item we are searching for is less than the middle item, we can simply perform a binary search of the left half of the original list. Likewise, if the item is greater, we can perform a binary search of the right half. Either way, this is a recursive call to the binary search function passing a smaller list.

Recursive Best First Search. The memory limitation of the heuristic path algorithm can be overcome simply by replacing the best-first search with IDA* search using the sure weighted evaluation function, with w>=1/2.. IDA* search is no longer a best-first search since the total cost of a child can beless than that of its parent, and thus nodes are not necessarily expanded in best-first order.
