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