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

Try widening your search to All Fields.

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 response estimation algorithmss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified parameters estimation algorithms") OR ("modified response estimation algorithmss")).
• Removing quotes may allow a broader search: (( modified parameters estimation algorithms ) or ( modified response estimation algorithmss )).
• Adding a wildcard symbol may retrieve word variants: (("modified parameters estimation algorithms") or ("modified response estimation algorithmss"))*.
