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

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