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