Someone mentioned what I think was referred to as 'logical distance'.

My hard drive crashed and I dont have the link anymore.

I do recall that I ran across it on this site, in response to linking algorithmic complexity to information theory.

It was a link to a University of Chicago researcher, and dealt with this field. I think also that computational neuroscience people use it.

Tried searching online and here but no luck.

If this rings a bell for anyone please direct me to that topic.

I’m almost sure that this link is what you are looking for, especially the answer by @Joshua Grochow. As you can see it was not on this site but on a sister site. Moreover, the notion mentioned was not “logical distance” but “logical depth”. Nevertheless, the notion of “logical distance” is really closely related to “logical depth” – see here.
