Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithm", "modified multiobjective optimizer algorithms"
"machinery using methods algorithm" » "machines using methods algorithm", "machinery nursing methods algorithm", "machinery making methods algorithm", "machinery counting 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: (("modified multiobjective optimized algorithms") OR ("machinery using methods algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified multiobjective optimized algorithms\") OR (\"machinery using methods algorithm\"))*".
• Removing quotes may allow a broader search: (( modified multiobjective optimized algorithms ) OR ( machinery using methods algorithm ))*.
