Perhaps you should try some spelling variations:
"modified motion optimization algorithms" » "modified motion optimisation algorithm", "modified motion estimation algorithms", "modified motion estimation algorithm", "modified motion optimisation algorithms", "modified motion estimation algorithmss", "modified policy optimization algorithms", "modified allocation optimization algorithms"
"modified parameters optimization algorithm" » "modified parameter optimization algorithm", "modified parameter estimation algorithm", "modified parameters optimisation algorithm", "modified parameters estimation algorithm", "modified parameters estimation 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 motion optimization algorithms\") OR (\"modified parameters optimization algorithm\"))~".
• Removing quotes may allow a broader search: (( modified motion optimization algorithms ) OR ( modified parameters optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified motion optimization algorithms") OR ("modified parameters optimization algorithm"))*.
