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