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 objective estimation algorithms" » "modified objective estimation algorithm", "modified objective optimization algorithms", "modified objective optimisation algorithm", "modified objective allocation algorithms"

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 objective estimation algorithms\") OR (\"modified response estimation algorithmss\"))~".
• Removing quotes may allow a broader search: (( modified objective estimation algorithms ) OR ( modified response estimation algorithmss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective estimation algorithms") OR ("modified response estimation algorithmss"))*.
