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