I missed Wayne's posting since the subject line had nothing to do
with fuzzy logic, and although I know that I will raise a chorus of
outrage I am changing the subject line.
Quite a few papers on fuzzy logic aplications have been published,
many in Ecological Modelling (including a couple of my own). I also
have some PowerPoint presentations on my website,
http://ciencia.silvert.org, and there are many in related fields
such as soil science. I think that one of my first efforts was in
niche theory, obviously the "multi-dimensional manifold" that
Hutchinson defined must have fuzzy boundaries.
Unfortunately a lot of work in the field seems to consist of lots of
mathematics with little biological content. I like to think in terms
of fuzzy rules like
IF the weather is warm AND nutrient levels are high THEN there is a
serious risk of bottom anoxia
In what way is that fuzzy logic? The truth value of the statement above,
Pr(Z|X & Y) > Pr(Z|!(X & Y))
is surely 1. Where is the fuzzy logic element?
I'm confused.
