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