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 method algorithm" » "mobile learning mom algorithm", "machine learning method algorithm", "mobile learning methods algorithm", "mobile graining methods algorithm", "mobile learning emotion algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("mobile learning method algorithm") OR ("modified allocation estimation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"mobile learning method algorithm\") OR (\"modified allocation estimation algorithms\"))".
• Removing quotes may allow a broader search: (( mobile learning method algorithm ) OR ( modified allocation estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("mobile learning method algorithm") OR ("modified allocation estimation algorithms"))*.
