Perhaps you should try some spelling variations:
"modified motion optimization algorithmss" » "modified motion optimization algorithms", "modified motion optimisation algorithm", "modified motion estimation algorithm", "modified motion estimation algorithmss", "modified policy optimization algorithmss", "modified allocation optimization 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"

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 motion optimization algorithmss"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified parameters estimation algorithms\") OR (\"modified motion optimization algorithmss\"))".
• Removing quotes may allow a broader search: (( modified parameters estimation algorithms ) OR ( modified motion optimization algorithmss )).
• Adding a wildcard symbol may retrieve word variants: (("modified parameters estimation algorithms") OR ("modified motion optimization algorithmss"))*.
