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