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 solution algorithm" » "code learning evolution algorithm", "code learning convolution algorithms", "code learning evolutionary algorithm", "code learning convolution algorithm", "code learning emotion algorithm", "how learning solution algorithm"

Try widening your search to All Fields.

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 optimized algorithm") or ("code learning solution algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified multiobjective optimized algorithm") OR ("code learning solution algorithm")).
• Removing quotes may allow a broader search: (( modified multiobjective optimized algorithm ) or ( code learning solution algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimized algorithm") or ("code learning solution algorithm"))*.
