Perhaps you should try some spelling variations:
"modified parameter estimation algorithmss" » "modified parameter estimation algorithm", "modified parameter optimization algorithms", "modified parameter estimation algorithms", "modified parameter optimization algorithmss", "modified parameter optimisation algorithms", "modified parameter estimates algorithmss"
"modified response estimation algorithms" » "modified response estimation algorithm", "modified response optimization algorithms", "modified response optimisation algorithm", "modified pose estimation algorithms", "modified response association algorithms"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified response estimation algorithms") OR ("modified parameter estimation algorithmss"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified response estimation algorithms\") OR (\"modified parameter estimation algorithmss\"))".
• Removing quotes may allow a broader search: (( modified response estimation algorithms ) OR ( modified parameter estimation algorithmss )).
• Adding a wildcard symbol may retrieve word variants: (("modified response estimation algorithms") OR ("modified parameter estimation algorithmss"))*.
