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