[Insight-users] LBFGSOptimizer bug (?)

[Tim Allman]

I have come across some odd behaviour with the LBFGSOptimizer.

In my project I have been using ITK 4.3 debug build libraries with good 
results. The trace printout indicated normal convergence and a call to  
GetStopConditionDescription() indicated "LBFGSOptimizer: Function 
tolerance reached".

However, when I switched to the release build, 
GetStopConditionDescription()  returned "LBFGSOptimizer: Failure". I dug 
into the call with my debugger and the problem seems to lie in the 
vnl_lbfgs code.

Is anyone aware of this behaviour? Is there a work around?

Thanks,

Tim
