If you use optim you can set the ind retured arg to -1 in the cost
function to say that the function cannot be evaluated at this point.

Hi All
I’m using Scilab as the interface between my optimizer and my finite
element solver(s) and sometimes Scilab stops because of unexpected and
impossible calculus (1/x with x = 0 as an example ); obviously Scilab
stops (and so the optimization).
I’m wondering if it’s possible:
-To ask back Scilab a message such as “hey I crashed because you’re a
fool and you’ve not anticipated an impossible calculation !!!”
-To get back Scilab control in order to avoid optimization process
crash ? I’ve been thinking in affecting a cost function value at %inf
for example (not elegant I recognize)
I don’t know if I’m understandable enough …
