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"
"modified learning solution algorithm" » "modified learning convolution algorithms", "modified learning evolutionary algorithm", "modified learning estimation algorithm", "mobile learning solution algorithm", "modified caging solution algorithm", "modified learning convolution algorithm", "modified learning emotion 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 objective evolution algorithm") OR ("modified learning solution algorithm"))~.
• Removing quotes may allow a broader search: (( modified objective evolution algorithm ) or ( modified learning solution algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective evolution algorithm") or ("modified learning solution algorithm"))*.
