Perhaps you should try some spelling variations:
"modified game optimisation algorithm" » "modified game optimization algorithms", "modified game estimation algorithm", "modified game optimization algorithm", "modified stage optimization algorithm", "modified _ optimisation algorithm", "modified male optimisation algorithm", "modified adam optimisation algorithm"
"modified notion estimation algorithms" » "modified notion estimation algorithm", "modified notion optimization algorithms", "modified notion approximation algorithms", "modified motion estimation algorithms"

Try widening your search to All Fields.

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

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