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

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