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