Ah, mira, açò vindría a donar-me la raó sobre el que dic sovint sobre el 
tema del sorroll en aquesta llista. És clar, que una cosa es una xarxa 
d'interaccións neuronals i una altre és el que pugui ser aquesta 
llista... però bé, sempre es bò trobar-ne coses comuns. Tu creus calamar 
que aquest postulat sería aplicable aquí, idò?

Què és un "bistable system"? i un "local minimum"? M'encanten els 
paralelistmes que puguin haver entre la biología i el wetware que 
poguesim estar ejecutant aquí, però no sé a què et refereixes, calamarix 
:) Explica't una mica, va, que em sembla molt interessant...


pd: molt bona la indirecta del "caos" ;)
