Merge Sort - Natural Merge Sort

Natural Merge Sort

A natural merge sort is similar to a bottom up merge sort except that any naturally occurring runs (sorted sequences) in the input are exploited. In the bottom up merge sort, the starting point assumes each run is one item long. In practice, random input data will have many short runs that just happen to be sorted. In the typical case, the natural merge sort may not need as many passes because there are fewer runs to merge. For example, in the best case, the input is already sorted (i.e., is one run), so the natural merge sort need only make one pass through the data.

Famous quotes containing the words natural, merge and/or sort:

    “When a natural discourse paints a passion or an effect, one feels within oneself the truth of what one reads, which was there before, although one did not know it. Hence one is inclined to love him who makes us feel it, for he has not shown us his own riches, but ours.”
    —Blaise Pascal (1623–1662)

    “Traditionally in American society, men have been trained for both competition and teamwork through sports, while women have been reared to merge their welfare with that of the family, with fewer opportunities for either independence or other team identifications, and fewer challenges to direct competition. In effect, women have been circumscribed within that unit where the benefit of one is most easily believed to be the benefit of all.”
    —Mary Catherine Bateson (b. 1939)

    “This sort of adoration of the real
    Is but a heightening of the beau ideal.”
    —George Gordon Noel Byron (1788–1824)
