Perhaps you should try some spelling variations:
"modified static optimization algorithms" » "modified static optimisation algorithm", "modified static estimation algorithms", "modified static estimation algorithm", "modified stage optimization algorithms", "modified stochastic optimization algorithms", "modified staffing 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: "((\"modified static optimization algorithms\") OR (\"mobile learning method algorithm\"))~".
• Removing quotes may allow a broader search: (( modified static optimization algorithms ) OR ( mobile learning method algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified static optimization algorithms") OR ("mobile learning method algorithm"))*.
