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