Perhaps you should try some spelling variations:
"modified notion optimization algorithms" » "modified notion optimisation algorithm", "modified notion estimation algorithms", "modified notion estimation algorithm", "modified network optimization algorithms", "modified policy optimization algorithms", "modified allocation optimization algorithms"
"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.

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