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