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