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