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