Perhaps you should try some spelling variations:
"modified parameters optimization algorithms" » "modified parameter optimization algorithms", "modified parameter estimation algorithms", "modified parameters optimisation algorithm", "modified parameters estimation algorithms", "modified parameters estimation algorithm"
"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.

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