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