βΊA frequent problem with contour integrals is heavy cancellation, which occurs especially when the value of the integral is exponentially small compared with the
maximum absolute value of the integrand.
To avoid cancellation we try to deform the path to pass through a saddle point in such a way that the
maximum contribution of the integrand is derived from the neighborhood of the saddle point.
