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