[ji...] Posted April 24 Share Posted April 24 Hello, if i click on the MMB, sometimes the results are worse. Someone can tell me what happened?? Crazy!!!!2.JPG1.JPG Link to comment Share on other sites More sharing options...
[Da...] Posted April 24 Share Posted April 24 The result shouldn't be worse, but as you can see in the dialog box with the MMB calculation, there's also a field that allows you to alter the number of iterations. An MMB calculation is mathematically complex and can't be solved analytically, only numerically. That means that it takes a number of repeated steps or iterations to get to the best solution. Maybe three iterations are not enough in your case to get the optimum solution. Link to comment Share on other sites More sharing options...

No. The mathematics behind certain calculations like MMB calculations are so complex, that they don't yield one and only one exact result. Instead, each step of the calculation (and those steps are called iterations) only get closer to the best result. An iterative or looped alignment is just another example of this slow convergence to the best result. The dialog box of the line profile allows for increasing the number of mathematical steps (or iterations) for the MMB calculation to achieve the best result. If you increase the number of iterations, the result might get closer and closer to the result without MMB or even get better than that. There's only one drawback of more iterations: the calculation might take longer time. Link to comment Share on other sites More sharing options...

If someone can confirm or correct me, I would appreciate it. Link to comment Share on other sites More sharing options...
[Cl...] Posted April 24 Share Posted April 24 I started out programming on Virtual DMIS back in 2002 and that software used what they called an "Iterative Alignment". It was not (to my knowledge) a German company. Link to comment Share on other sites More sharing options...
