Default Numerical Optimizers for LTSpice

As far as I know there are 2 numerical optimizer available for LTSpice IV.
ASCO project :: homepage
and
http://www.evospice.site88.net/evospice/evospice.html

I think you actually have to compile c source code to get the ASCO optimizer working but maybe someone has a pre-built version available.
The EvoSpice one is only available in a very limited trial version.
Take your pick!

EvoSpice 4.1 is available for free and there is a example of how to measure harmonic distortion and use it as an objective for optimization.

There is an optimizer perl script floating around the LTSpice group website as well.
I don't know how they stack up against each other as I ain't goin' to run a perl script and I ain't goin' to hard code data into a c file with ASCO to find out.
For ac analysis only there is Circuit Mason
Similar to EvoSpice that also includes an evolutionary algorithm
