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.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"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"))*.
