Perhaps you should try some spelling variations:
"modified parameters optimization algorithmss" » "modified parameters optimisation algorithm", "modified parameters estimation algorithms", "modified parameters estimation algorithm", "modified parameters optimisation algorithms", "modified parameters estimation algorithmss", "modified parameter optimization algorithmss", "modified parameter estimation algorithmss"
"defined network optimization algorithms" » "defined network optimisation algorithm", "defined network estimation algorithms", "defined network estimation algorithm", "designed network optimization algorithms"

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