Perhaps you should try some spelling variations:
"modified objective evolution algorithm" » "modified objective evolutionary algorithm", "modified objective allocation algorithm", "modified objective convolution algorithms", "modified objective estimation algorithm"
"code learning solution algorithm" » "code learning convolution algorithms", "code learning evolutionary algorithm", "code learning estimation algorithm", "code learning convolution algorithm", "code learning emotion algorithm", "how learning solution algorithm"

You may be able to get more results by adjusting your search query.

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