 Sorting algorithms are often referred to as a word followed by the word "sort" and grammatically are used in English as noun phrases, for example in the sentence, "it is inefficient to use insertion sort on large lists" the phrase "insertion sort" refers to the insertion sort sorting algorithm.From the beginning of computing, the sorting problem has attracted a great deal of research, perhaps due to the complexity of solving it efficiently despite its simple, familiar statement.Among the authors of early sorting algorithms around 1951 was Betty Holberton (née Snyder), who worked on ENIAC and UNIVAC.
