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