Perhaps you should try some spelling variations:
"modified game estimation algorithms" » "modified game optimization algorithms", "modified game optimisation algorithm", "modified game approximation algorithms", "modified pose estimation algorithms", "modified male estimation algorithms", "modified adam estimation algorithms"
"modified objective estimation algorithm" » "modified objective optimization algorithm", "modified objective allocation algorithm"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified objective estimation algorithm") OR ("modified game estimation algorithms"))~.
• Removing quotes may allow a broader search: (( modified objective estimation algorithm ) or ( modified game estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective estimation algorithm") or ("modified game estimation algorithms"))*.
