Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithm", "modified multiobjective optimizer algorithms"
"powder learning method algorithm" » "powder learning mom algorithm", "powder learning methods algorithm", "powder graining methods algorithm", "powder 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 (\"powder learning method algorithm\"))~".
• Removing quotes may allow a broader search: (( modified multiobjective optimized algorithms ) OR ( powder learning method algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimized algorithms") OR ("powder learning method algorithm"))*.
