The respective termination criteria are as described in Figure . with no optimisation failures, and only a few sub-optimal points identified in TP1 and TP3. Reasons for non-convergence in these cases can be attributed to small discontinuities in the T M F close to the optimal solution of the parameter estimation problem. Even then, the sub-optimal points in TP1 and TP3 achieve objective function values within < 1% of the lowest minimum found by the remaining optimisations.
