An analysis of the loop optimization scores in knuth's ‘empirical study of FORTRAN programs’
David C. Hoaglin · Software Practice and Experience · 1973
Abstract The optimization scores for Knuth's random sample of inner loops are analysed to provide a unified comparison of the five optimization levels. The techniques used are those of exploratory data analysis, and their role in the analysis is discussed. As a consequence of the analysis, five rough groups of programs with different optimization behaviour are identified and tentatively characterized.
