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