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