I wonder if there’s any tool/website where I can plot some run times as graphs. Because, the asymptotic notation is often not what I wanted i.e. Don’t want to ignore constants.
For example, suppose I have two notations, like:
1) O = (n * log n).
2) O = (n * log n * log n)/5.
It’s obvious that 1st one is asymptotically better. But what I want to see how they perform and at which point the second one starts to become better.
A graphical notation where I can enter different equations and plot them them to see how they vary would be greatly useful for this purpose. In my search I found this site where they have some plots. I am looking for something similar but I also want to input my equations to plot to analyse the performance for various ‘n’ values.
As soon as you stop “ignoring constants”, you’re no longer graphing “Big O” notation, but just performing a standard XY plot. As such, any graphing program, even online graphing calculators, would let you display this, just replace “n” for “X” and you’ll get the proper graph.
