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