Perhaps you should try some spelling variations:
"modified pose estimation algorithmssssss" » "modified pose estimation algorithm", "modified pose estimation algorithmsssss", "modified pose optimization algorithmssssss", "modified pose optimisation algorithmsssss", "modified male estimation algorithmssssss", "modified passive estimation algorithmssssss"
"modified objective estimation algorithms" » "modified objective estimation algorithm", "modified objective optimization algorithms", "modified objective optimisation algorithm", "modified objective allocation algorithms"

Try widening your search to All Fields.

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

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