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