Perhaps you should try some spelling variations:
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
optimized algorithm » optimized algorithms, optimizer algorithms
changing optimized » choosing optimizer
modified changing » modified caging
modified pose » modified male, modified passive

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (( modified pose estimation algorithms ) or ( modified changing optimized algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( modified pose estimation algorithms ) OR ( modified changing optimized algorithm )).
• Adding a wildcard symbol may retrieve word variants: (( modified pose estimation algorithms ) or ( modified changing optimized algorithm ))*.
