Hello,
The implementation of the algebra_solver fails to return root values for a function I am investigating. I initially augment the algebra_solver with a bisection method, i.e. bisection method pre-solves the function, then uses the output as the initial value for the algebra solver… This seems to work better, but it is not a be-all-end-all, i.e. I am still getting wrong roots even if the bisection method hones into the approximate roots.
The function I am solving works well with bracketing methods-- I have tested other root solving routines on MATLAB such as regula falsi, secant and newton-raphson, but gradient based methods fail for some combination of the target function parameters-- I understand that the algebra_solver uses first-order derivatives as well.
What else should I consider for this problem?
