Perhaps you should try some spelling variations:
"modified allocation estimation algorithms" » "modified allocation optimization algorithms", "modified motion estimation algorithms", "modified allocation estimation algorithm", "modified allocation optimisation algorithm"
"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"

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