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