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