Hello list,

Im currently working on a composition based on a proces. Ive got a problem that i cant seem to find my way around. This particular model is a bird that has several parameters determining whether or not it his going to be atracted to our particular location. (Somewhereland). To do this it first determines its charachter (is it a seasonal migrator i.e.). etc. Another one is the food/competitor ratio. I need the bird to see that if A) The food/competitor ratio = 0 (meaning: no new birds can be fed from this supply) B) he checks whether or not he is currently present

so that if a * b = 1 He can stay, and if a * b = 0 he will not go to Somewhereland.

but because the output would be immediatly fed back to B it creates a stack overflow. I thought i could get around this by have a metro send out the occasional update of his current presence.

Any hints would be much appreciated.

Thanks Anton
