Perhaps you should try some spelling variations:
"modified multiobjective estimation algorithm" » "modified multiobjective optimization algorithm"
"machines graining methods algorithm" » "machine learning methods algorithm", "machines learning methods algorithm", "machines learning method algorithm", "machines making methods algorithm"

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

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