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