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