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

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