Perhaps you should try some spelling variations:
"modified multiobjective estimation algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective estimation algorithm", "modified multiobjective optimisation algorithm"
"modified pose estimation algorithmssss" » "modified pose estimation algorithm", "modified pose estimation algorithmsss", "modified pose optimization algorithmssss", "modified pose optimisation algorithmsss", "modified male estimation algorithmssss", "modified passive estimation algorithmssss"

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