Perhaps you should try some spelling variations:
"modified multiobjective estimation algorithm" » "modified multiobjective optimization algorithm"
"modified pose optimisation algorithmss" » "modified pose optimisation algorithm", "modified pose optimization algorithms", "modified pose estimation algorithms", "modified qoe optimization algorithmss", "modified _ optimisation algorithmss", "modified pose estimation algorithmss", "modified male optimisation algorithmss", "modified passive optimisation algorithmss"

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