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

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