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