Perhaps you should try some spelling variations:
"modified notion optimized algorithms" » "modified notion optimized algorithm", "modified notion optimizer algorithms", "modified notion optimization algorithms"
"mobile learning evolution algorithm" » "mobile learning solution algorithm", "mobile learning evolutionary algorithm", "mobile learning convolution algorithms", "mobile learning convolution algorithm", "mobile learning emotion algorithm", "machine learning evolution 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 notion optimized algorithms") or ("mobile learning evolution algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified notion optimized algorithms") OR ("mobile learning evolution algorithm")).
• Removing quotes may allow a broader search: (( modified notion optimized algorithms ) or ( mobile learning evolution algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified notion optimized algorithms") or ("mobile learning evolution algorithm"))*.
