Here's how Twiddle works.

Laurent asked another question about twiddle.

This is Twiddle. Let me put this into pictures.

Another question from George about twiddle is local minima.

In Twiddle, we're trying to optimize for a set of parameters.

He wants to know, first, is twiddle really all that good?

But yes, there are many, many ways to improve over twiddle.

That's where Twiddle comes in. It's a really smart algorithm, I believe.

We had a lot of great questions on twiddle and parameter optimization.

It seems like with twiddle we're adjusting one parameter at a time.

In a lot of cases where twiddle would fail other methods would succeed.

That's a fantastic question that a case where twiddle will just fail you.

Say I wanted to implement Twiddle so as to minimize the average crosstrack error.

Instead of twiddle I'm just going to give you parameters, 10, 15, and 0.

You can write a PhD thesis about this, but the nice thing is twiddle takes no time to implement, and I've never seen a piece of code that couldn't be made better with a twiddle around it.

Are they a problem with twiddle? It seems like it's pretty easy to get caught in one.

The easiest fixes, if you have happen to know the direction, the can twiddle in that direction.

Those work fine for me, and they're actually the result of running twiddle without the integral part.

Again, twiddle was only given because it's so simple, and I hope you found it to be very effective.

On Macs, Safari supports WebGL but you'll have to do a little twiddle to enable it. Linux has it's own issues.

I should warn you these are about the best variables I could find, but I didn't really apply twiddle to this.

It was partially given because I couldn't figure out what the right control parameters are, so I just implemented this twiddle thing.

Dinner will be served at 8 00 with a Portuguese wine spelled DAO with a twiddle over the A and pronounced dang.

That's the core of Twiddle, and what it really does is for each coordinate in isolation it moves our parameter down a little bit by this value over here.

When you apply twiddle and try this, you will find that it's hard to apply because your function might never return, so you have to build in the time somehow.

He worked nights at Vauxhall Motors in Luton and demanded total silence throughout the house, so that when we came home from school at 3 30 in the afternoon, we would huddle beside the TV, and rather like safe crackers, we would twiddle with the volume control knob on the TV so it was almost inaudible.
