  The question of whether it is possible to compute scattering resonances of
Schr\"odinger operators - independently of the particular potential - is
addressed. A positive answer is given, and it is shown that the only
information required to be known a priori is the size of the support of the
potential. The potential itself is merely required to be $\mathcal{C}^1$. The
proof is constructive, providing a universal algorithm which only needs to
access the values of the potential at any requested point.
