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