Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithm", "modified multiobjective optimizer algorithms"
"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.

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