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

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 game estimation algorithms") OR ("modified objective optimisation algorithm"))~.
• Removing quotes may allow a broader search: (( modified game estimation algorithms ) or ( modified objective optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified game estimation algorithms") or ("modified objective optimisation algorithm"))*.
