I want to compare two algorithms. I need the empirical data of their CPU
time. How can I do it? use special software or programming it myself using
some specific functions?

if on unix, you can use the 'time' utility to get the cpu time of your running.
if you do FORTRAN, it has a function (forgot the name) which can let you get
the cpu time. you can search for it.
