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