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

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 estimation algorithm\") OR (\"modified objective optimizer algorithmsss\"))~".
• Removing quotes may allow a broader search: (( modified parameters estimation algorithm ) OR ( modified objective optimizer algorithmsss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified parameters estimation algorithm") OR ("modified objective optimizer algorithmsss"))*.
