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