The efficiency of an algorithm is measured by a runtime function T ( n ) . n is the size of the input. Strictly speaking, n is the # of bits needed to represent input. Commonly, n is the # of items in the input, if each item is of fixed size . c Xin He (University at Buffalo) CSE 431/531 Algorithm Analysis and Design 2 / 29 Algorithm Analysis It means: estimating the recourses required.
