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