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