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