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