Perhaps you should try some spelling variations:
"verified network optimization algorithmss" » "verified network optimization algorithms", "verified network optimisation algorithm", "verified network estimation algorithms", "verified network optimization algorithmsss", "verified network optimisation algorithmss", "verified network estimation algorithmss", "certified network optimization 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"

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified parameters optimization algorithm") or ("verified network optimization algorithmss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified parameters optimization algorithm") OR ("verified network optimization algorithmss")).
• Removing quotes may allow a broader search: (( modified parameters optimization algorithm ) or ( verified network optimization algorithmss )).
• Adding a wildcard symbol may retrieve word variants: (("modified parameters optimization algorithm") or ("verified network optimization algorithmss"))*.
