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:
“It has no share in the leadership of thought: it does not even reflect its current. It does not create beauty: it apes fashion. It does not produce personal skill: our actors and actresses, with the exception of a few persons with natural gifts and graces, mostly miscultivated or half-cultivated, are simply the middle-class section of the residuum.”
—George Bernard Shaw (1856–1950)
“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)
“What sort of men are these? How do they do it? How can they do it?”
—Samuel Fuller, U.S. screenwriter, and Milton Sperling. Samuel Fuller. Doc (Andrew Duggan)
