Algorithm Analysis

Algorithm Analysis. Algorithm Efficiency and Big-O. Getting a precise measure of the performance of an algorithm is difficult Big-O notation expresses the performance of an algorithm as a function of the number of items to be processed This permits algorithms to be compared for efficiency.

Remember

Remember. Performance is specific to a particular program/s Total execution time is a consistent summary of performance For a given architecture performance increases come from: increases in clock rate (without adverse CPI affects) improvements in processor organization that lower CPI
