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