Perhaps you should try some spelling variations:
"modified notion optimization algorithmssss" » "modified notion optimization algorithms", "modified notion optimisation algorithm", "modified network optimization algorithmssss", "modified policy optimization algorithmssss", "modified allocation optimization algorithmssss"
"modified static estimation algorithms" » "modified static estimation algorithm", "modified static optimization algorithms", "modified static optimisation algorithm"

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 static estimation algorithms") OR ("modified notion optimization algorithmssss"))~.
• Removing quotes may allow a broader search: (( modified static estimation algorithms ) or ( modified notion optimization algorithmssss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified static estimation algorithms") or ("modified notion optimization algorithmssss"))*.
