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