Could someone tell me what criteria is used in FindRoot to terminate
the search?
I'm running FindMinimum on
a function that does not have local minima yet it terminates. I've
tried upping the MaxIterations and the AccuracyGoal but the results
don't seem to improve.
For example :
numerical_solution = FindRoot[f[x]==0, {x, {0,1}},
AccuracyGoal->0.001];
If exact solution is name exact_solution,
is Findroot exit the search when :
abs(numerical_solution - exact_solution) < 0.001 ???
or when :
abs[f[numerical_solution ] - f[exact_solution]] < 0.001 ???
or others ?
Thanks in advance,
Eric
