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 optimized algorithmss" » "modified objective optimized algorithms", "modified objective optimized algorithm", "modified objective optimizer algorithms", "modified objective optimal algorithmss", "modified objective optimization algorithmss"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified parameters optimization algorithms") OR ("modified objective optimized algorithmss"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified parameters optimization algorithms\") OR (\"modified objective optimized algorithmss\"))*".
• Removing quotes may allow a broader search: (( modified parameters optimization algorithms ) OR ( modified objective optimized algorithmss ))*.
