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