Perhaps you should try some spelling variations:
"modified notion estimation algorithmsss" » "modified notion estimation algorithm", "modified notion estimation algorithmss", "modified notion optimization algorithmsss", "modified notion optimisation algorithmss", "modified motion estimation algorithmsss"
"modified objective estimation algorithms" » "modified objective estimation algorithm", "modified objective optimization algorithms", "modified objective optimisation algorithm", "modified objective allocation 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 algorithmsss") or ("modified objective estimation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified notion estimation algorithmsss") OR ("modified objective estimation algorithms")).
• Removing quotes may allow a broader search: (( modified notion estimation algorithmsss ) or ( modified objective estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified notion estimation algorithmsss") or ("modified objective estimation algorithms"))*.
