Perhaps you should try some spelling variations:
"modified multiobjective optimizer algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithms", "modified multiobjective optimized algorithm"
"code learning evolution algorithm" » "code learning solution algorithm", "code learning evolutionary algorithm", "code learning convolution algorithms", "code learning convolution algorithm", "code learning emotion algorithm", "how learning evolution 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 multiobjective optimizer algorithms") OR ("code learning evolution algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified multiobjective optimizer algorithms\") OR (\"code learning evolution algorithm\"))".
• Removing quotes may allow a broader search: (( modified multiobjective optimizer algorithms ) OR ( code learning evolution algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimizer algorithms") OR ("code learning evolution algorithm"))*.
