Perhaps you should try some spelling variations:
"modified notion optimization algorithmsss" » "modified notion optimization algorithms", "modified notion optimisation algorithm", "modified network optimization algorithmsss", "modified policy optimization algorithmsss", "modified allocation optimization algorithmsss"
"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 notion optimization algorithmsss"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified parameters estimation algorithms\") OR (\"modified notion optimization algorithmsss\"))".
• Removing quotes may allow a broader search: (( modified parameters estimation algorithms ) OR ( modified notion optimization algorithmsss )).
• Adding a wildcard symbol may retrieve word variants: (("modified parameters estimation algorithms") OR ("modified notion optimization algorithmsss"))*.
