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