Perhaps you should try some spelling variations:
"modified multiobjective optimisation algorithms" » "modified multiobjective optimization algorithms", "modified objective optimization algorithms", "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithms", "modified multiobjective estimation algorithm"
"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"

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 optimization algorithms") OR ("modified multiobjective optimisation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified game optimization algorithms\") OR (\"modified multiobjective optimisation algorithms\"))".
• Removing quotes may allow a broader search: (( modified game optimization algorithms ) OR ( modified multiobjective optimisation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified game optimization algorithms") OR ("modified multiobjective optimisation algorithms"))*.
