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