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