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