Perhaps you should try some spelling variations:
"modified multiobjective estimation algorithm" » "modified multiobjective optimization algorithm"
"mapping learning method algorithm" » "machine learning method algorithm", "enabling learning method algorithm", "mapping learning mom algorithm", "mapping learning methods algorithm", "mapping graining methods algorithm", "mapping learning emotion algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("mapping learning method algorithm") OR ("modified multiobjective estimation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"mapping learning method algorithm\") OR (\"modified multiobjective estimation algorithm\"))*".
• Removing quotes may allow a broader search: (( mapping learning method algorithm ) OR ( modified multiobjective estimation algorithm ))*.
