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

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