System Profiler and Benchmark

Comparing with a superstar is the wrong benchmark.

You could assume that every possible input array is equally unlikely, and then analyze the average running time of an algorithm.

The lesson from that was that it was Africa an African story that was used to share news with the rest of the world of what the benchmark can be for corporate turnarounds.

Here are the rates you find, 25 frames per second for 100 frames then 50 frames per second for a hundred frames then 25 frames per second for the next hundred frames then 10 frames per second for the last hundred frames of your benchmark.

So it's going to look something like, I'm going to try my best to, it's going to look something like that.

You will be better soon.

Now we're gonna have you back on your feet in a sec.

By benchmarks, I just mean that one agrees up front about some set, say ten or twenty, Benchmark inputs, which are thought to represent practical or typical inputs for the algorithm.

That could be helpful to both of us.

You can't miss it.

You can not miss it.

You'll understand it right away.

All in good time. Now...

Are you sure you want to sell?

And so that makes it denser and heavier.

That would be a good opportunity to do some publicity.

And happily, another bonus of doing worst case analysis, as we will in this course, it's usually mathematically much more attractable than trying to analyze the average performance of an algorithm under some distribution over inputs.

There is no free market for oil.

Or if you have a parabola like, x is equal to y squared.

And a little bit faster than y is equal to minus x squared.

And then down 8.

So let me draw the line of y is equal to 0.

And then let me split this into three columns.

It's kind of the classic U shaped parabola that

Now if I were to graph f of x, the graph is going to

LG Ten of diamonds, yeah.

And let's say we don't know what g of x is.

If you haven't you can graph it by trying some points.

This is the probability that A at time t 1 goes to A at time t.

We'd enjoy having you.

Let's draw that surface.

So on the xy axis, kind of the domain you can view it that

So if I draw that asymptote, it'll look something

So a is 1, 2.

Vector b is 0, 3.

So if you add 3a to minus 2b, we get to this vector.

So 1 and 1 2 a minus 2b would still look the same.

So if this is my new plane whoops.

Let me see if I can draw it.

What that means is, a 200 megabyte file

So the inverse graph is going to look something like this.

So it's going to look something like that.

They'd think you had been off on a hell of a toot.
