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