Perhaps you should try some spelling variations:
"modified objective optimization algorithms" » "modified objective optimisation algorithm", "modified objective estimation algorithms", "modified objective estimation algorithm", "modified multiobjective optimization algorithms"
"modified policy estimation algorithmss" » "modified policy estimation algorithms", "modified policy estimation algorithm", "modified policy optimization algorithmss", "modified pose estimation algorithmss", "modified motion estimation algorithmss"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified objective optimization algorithms") OR ("modified policy estimation algorithmss"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified objective optimization algorithms\") OR (\"modified policy estimation algorithmss\"))".
• Removing quotes may allow a broader search: (( modified objective optimization algorithms ) OR ( modified policy estimation algorithmss )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimization algorithms") OR ("modified policy estimation algorithmss"))*.
