Perhaps you should try some spelling variations:
"modified multiobjective estimation algorithm" » "modified multiobjective optimization algorithm"
"modified notion optimization algorithms" » "modified notion optimisation algorithm", "modified notion estimation algorithms", "modified notion optimized algorithms", "modified network optimization algorithms", "modified policy optimization algorithms", "modified allocation optimization 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 notion optimization algorithms") OR ("modified multiobjective estimation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified notion optimization algorithms\") OR (\"modified multiobjective estimation algorithm\"))*".
• Removing quotes may allow a broader search: (( modified notion optimization algorithms ) OR ( modified multiobjective estimation algorithm ))*.
