Perhaps you should try some spelling variations:
"mobile learning solution algorithm" » "mobile learning evolution algorithm", "mobile learning convolution algorithms", "mobile learning evolutionary algorithm", "mobile learning convolution algorithm", "mobile learning emotion algorithm", "machine learning solution algorithm"
"modified objective allocation algorithmss" » "modified objective location algorithmss"

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 allocation algorithmss") OR ("mobile learning solution algorithm"))~.
• Removing quotes may allow a broader search: (( modified objective allocation algorithmss ) or ( mobile learning solution algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective allocation algorithmss") or ("mobile learning solution algorithm"))*.
