<P> For maximum efficiency we wish to minimize resource usage . However , the various resources ( e.g. time , space ) can not be compared directly , so which of two algorithms is considered to be more efficient often depends on which measure of efficiency is considered the most important , e.g. the requirement for high speed , minimum memory usage or some other performance benchmark . </P>
what are the parameters to judge the efficiency of an algorithm
which measure of efficiency is considered the most important , e.g. the requirement for high speed , minimum memory usage or some other performance benchmark
