Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithm", "modified multiobjective optimizer algorithms"
"machines learning method algorithm" » "machine learning method algorithm", "active learning method algorithm", "mapping learning method algorithm", "machines learning mom algorithm", "machines learning methods algorithm", "machines graining methods algorithm", "machines learning emotion algorithm"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified multiobjective optimized algorithms\") OR (\"machines learning method algorithm\"))~".
• Removing quotes may allow a broader search: (( modified multiobjective optimized algorithms ) OR ( machines learning method algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimized algorithms") OR ("machines learning method algorithm"))*.
