Perhaps you should try some spelling variations:
"modified parameter optimization algorithms" » "modified parameter optimisation algorithm", "modified parameter estimation algorithms", "modified parameter estimation algorithm", "modified parameters optimization algorithms"
"modified objective optimizer algorithmsss" » "modified objective optimizer algorithms", "modified objective optimized algorithms", "modified objective optimized algorithm", "modified objective optimal algorithmsss", "modified objective optimization algorithmsss"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified parameter optimization algorithms") OR ("modified objective optimizer algorithmsss"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified parameter optimization algorithms\") OR (\"modified objective optimizer algorithmsss\"))".
• Removing quotes may allow a broader search: (( modified parameter optimization algorithms ) OR ( modified objective optimizer algorithmsss )).
• Adding a wildcard symbol may retrieve word variants: (("modified parameter optimization algorithms") OR ("modified objective optimizer algorithmsss"))*.
