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