Perhaps you should try some spelling variations:
"modified objective optimization algorithmssss" » "modified objective optimization algorithms", "modified objective optimisation algorithm", "modified multiobjective optimization algorithmssss"
"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.

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