Perhaps you should try some spelling variations:
"modified quadratic optimization algorithm" » "modified static optimization algorithm", "modified quadratic optimization algorithms", "modified quadratic optimisation algorithm", "modified quadratic estimation 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: (("modified quadratic optimization algorithm") OR ("mobile learning method algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified quadratic optimization algorithm\") OR (\"mobile learning method algorithm\"))".
• Removing quotes may allow a broader search: (( modified quadratic optimization algorithm ) OR ( mobile learning method algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified quadratic optimization algorithm") OR ("mobile learning method algorithm"))*.
