Perhaps you should try some spelling variations:
"modified network optimization algorithm" » "modified network optimization algorithms", "modified network optimisation algorithm", "modified network estimation algorithm", "certified network optimization algorithm", "defined network optimization algorithm", "modified near optimization 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"

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