Perhaps you should try some spelling variations:
"modified location estimation algorithmss" » "modified location estimation algorithms", "modified location estimation algorithm", "modified location optimization algorithms", "modified motion estimation algorithmss", "modified carbon estimation algorithmss"
"modified objective optimisation algorithm" » "modified objective optimization algorithm", "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective estimation algorithm", "modified objective 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 location estimation algorithmss") OR ("modified objective optimisation algorithm"))~.
• Removing quotes may allow a broader search: (( modified location estimation algorithmss ) or ( modified objective optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified location estimation algorithmss") or ("modified objective optimisation algorithm"))*.
