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 algorithms" » "modified made estimation algorithm", "modified made optimization algorithms", "modified made optimisation algorithm", "modified pose estimation algorithms", "modified male estimation algorithms", "modified adam estimation algorithms", "modified df estimation algorithms"

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

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