Perhaps you should try some spelling variations:
"modified objective optimization algorithm" » "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective optimisation algorithm", "modified objective estimation algorithm"
"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.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified objective optimization algorithm") OR ("code learning emotion algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified objective optimization algorithm\") OR (\"code learning emotion algorithm\"))".
• Removing quotes may allow a broader search: (( modified objective optimization algorithm ) OR ( code learning emotion algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimization algorithm") OR ("code learning emotion algorithm"))*.
