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"

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