Fitness Weighting 

I have found myself wishing I could set selection for vertical velocity as
inversely proportional to the frams performance.

I am hoping that fitness criteria set as

Vertical Position 1x
Vertical Velocity 1/x

Would help , in the early stages, for developing frams that move uphill
slowly, rather than frams that roll/jump/shuffle down the hill quickly...

ok, as soon as they start going uphill quickly it all goes wrong, but got to
get them going uphill first...

Am I right in this line of thinking?

Thanks,

Matt.

in the forthcoming v2.2, it will be

return 1.0/this.vertpos;

in v2.0,

move 1.0,m[m0]
div this.vertpos,m[m0]

as simple as that! but not "div-by-zero"-safe.
