Tikhonov regularization cutting out?

[aleaf]

Hi, I have two runs of the same problem, one using beopest64 and the other using pest++. phimlim is set to 125, but I get this behavoir in the pest++ run:

iteration	model_runs_completed	total_phi	measurement_phi	regularization_phi
0	0	511.412	511.295	0.116906
1	2155	280.338	280.157	0.181051
2	2294	3.13748e+06	250.639	3.13723e+06
3	2564	179.982	179.965	0.0171477
4	2834	151.611	151.611	9.51146e-07
5	3104	134.877	134.877	2.59368e-08
6	7408	124.774	124.774	1.81907e-08
7	7672	124.502	124.502	2.42814e-08
8	7936	120.759	120.759	1.99015e-08
9	8206	120.576	120.576	2.42924e-08
10	8476	120.552	120.552	2.49062e-08

Thanks for looking into this. Otherwise, great program. Really like the relinearization, FOSM uncertainty and improved output.
