Perhaps you should try some spelling variations:
"modified multiobjective estimation algorithm" » "modified multiobjective optimization algorithm"
"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"

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

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