Perhaps you should try some spelling variations:
"modified game estimation algorithms" » "modified game estimation algorithm", "modified game optimization algorithms", "modified game optimisation algorithm", "modified pose estimation algorithms", "modified male estimation algorithms", "modified adam estimation algorithms"
"modified notion approximation algorithms" » "modified network approximation algorithms", "modified time approximation algorithms", "modified one approximation 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 game estimation algorithms\") OR (\"modified notion approximation algorithms\"))~".
• Removing quotes may allow a broader search: (( modified game estimation algorithms ) OR ( modified notion approximation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified game estimation algorithms") OR ("modified notion approximation algorithms"))*.
