Perhaps you should try some spelling variations:
"modified rough approximation algorithm" » "modified rough approximation algorithms", "modified rough approximations algorithm", "modified one approximation algorithm"
"modified pose estimation algorithms" » "modified pose estimation algorithm", "modified pose optimization algorithms", "modified pose optimisation algorithm", "modified male estimation algorithms", "modified passive estimation algorithms"

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 rough approximation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified pose estimation algorithms") OR ("modified rough approximation algorithm")).
• Removing quotes may allow a broader search: (( modified pose estimation algorithms ) or ( modified rough approximation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified pose estimation algorithms") or ("modified rough approximation algorithm"))*.
