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