Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithm" » "modified multiobjective optimization algorithms", "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithm"
"modified policy estimation algorithmss" » "modified policy estimation algorithms", "modified policy estimation algorithm", "modified policy optimization algorithms", "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 multiobjective optimization algorithm") OR ("modified policy estimation algorithmss"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified multiobjective optimization algorithm\") OR (\"modified policy estimation algorithmss\"))".
• Removing quotes may allow a broader search: (( modified multiobjective optimization algorithm ) OR ( modified policy estimation algorithmss )).
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimization algorithm") OR ("modified policy estimation algorithmss"))*.
