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