WebThe decrease-by-a-constant-factor technique suggests reducing a problem instance by the same constant factor on each iteration of the algorithm. In most applications, this constant factor is equal to two. (Can you give an example of such an algorithm?) The decrease-by-half idea is illustrated in Figure 4.2. http://cs.yale.edu/homes/aspnes/pinewiki/DecreaseByConstant.html?highlight=%28CategoryAlgorithmNotes%29

WebJan 13, 2012 · Basically, the binary search algorithm just divides its work space (input (ordered) array of size n) into half in each iteration. Therefore it is definitely deploying the divide strategy and as a result, the time complexity reduces down to O (lg n).So,this covers up the "divide" part of it.
