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

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