Q: Stiff BVP of nonlinear ODE, shooting method and beyond

Boson BearI have been trying to solve this coupled ODE set. \begin{align} ( \frac{ \mu^2}{B} +1 ) \Phi^2 + \frac{1}{A} {\Phi^{\prime 2}} + \frac{1}{2}\lambda \Phi^4 - \frac{A'}{r A^2} + \frac{1}{r^2 A} - \frac{1}{r^2} &= 0, \cr ( \frac{\mu ^2 }{B} - 1 )\Phi^2 + \frac{1}{A} \Phi...
