Perhaps you should try some spelling variations:
"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"
"modified time approximation algorithms" » "modified one approximation algorithms", "modified _ approximation algorithms", "modified bi1 approximation algorithms", "modified male approximation algorithms"

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: (("code learning evolution algorithm") OR ("modified time approximation algorithms"))~.
• Removing quotes may allow a broader search: (( code learning evolution algorithm ) or ( modified time approximation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("code learning evolution algorithm") or ("modified time approximation algorithms"))*.
