Fang Cheng Leu, Yin-Te Tsai, Chuan Yi Tang [2000] have proposed an effective external sorting algorithm. This algorithm utilization Divide and Conquer procedure. This paper exhibits an ideal external sorting algorithm for two-level memory model. This system is not the same as the universal external merge sort and it utilizes the examining data to decrease the circle I/os in the outside stage. The algorithm is proficient, straightforward and it makes a great utilization of memory accessible in the late nature's turf. Under the certain memory demand, this algorithm runs with ideal number of disk I/os and each one record is precisely perused twice and composed twice.

Golam Rabiul Alma, Md. Amiruzzaman, S.m. Moinul Quadir [ 2004 ] have exhibited an Efficient Merge Sort Technique that lessens both Times and Comparisons. In this paper they proposed another however basic and productive merge sort technique. This technique has a few favorable circumstances on execution over past merge sort procedure. This procedure isolates the entire information as like separated and overcome strategy however until two components in an aggregation rather than one in each one gathering like conventional merge sort . At that point fathoms the isolated parts and overcomes them. The ensuing productivity of this technique is that the division of issue is a great deal less then the past strategy, so the recursive call is additionally less. Accordingly they have less examination & less computational …show more content…

In this paper, they apply Graph Structured Program Evolution (GRAPE) to development of general sorting algorithm. GRAPE is another Automatic Programming strategy. The representation of GRAPE is diagram structure, in this way it can express unpredictable projects (e.g. limbs and circles) utilizing its diagram structure. Each program is developed as a subjective administered chart of hubs and information set. GRAPE handles different information sorts utilizing information set for each one sort, and the genotype of GRAPE is the type of a direct series of whole numbers. The point of this work is to develop a project which rightly sort any arrangement of numbers. They show that GRAPE develops general sorting algorithm
