[Insight-users] Iteration Monitoring for LBFGSB optimization method

[BeneSchu]

hi,

the problem with the zeros of the optimizer->GetValue is solving with the
->GetCachedValue, but do you know how I can get only one value of each
iteration (with optimizer->GetCurrentIteration), is there also a method like
->GetCachedCurrentIteration ?

for example:

Starting Registration
0   0   0
0   0   0
0   0   0.000960382
1   0   0.000960382
1   0   0.00139707

the output I want:

Starting Registration

0   0.345   0.000960382
1   0.453   0.000960382

Could anyone give me some tipps?
Thanks!

Bene
