I'm working on a variational problem which calculates a maximum entropy
profile. The domain invariants of the system yield a 3X3 Nonlinear
system of Integral equations where the Lagrange multipliers in the
integrand are the unknowns. I have been trying to solve this system
using FindRoot but there is strong sensitivity to the initial guess and
I can't seem to get convergence. Any helpful hints based on this limited
