Nature of problem:
Resolve the thermodynamic Bethe ansatz equations corresponding to a factorized scattering theory and extract the data of the underlying conformal field theory reached in the ultraviolet limit.

Solution method:
Non linear multi-grid method with full adaptive scheme.

Running time:
Strongly dependent on the dimension of the system of coupled integral equations, see Table 1.
