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