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

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

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