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 network estimation algorithm" » "modified network optimization algorithm", "certified network estimation algorithm", "defined network estimation algorithm", "modified near estimation 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 network estimation algorithm\") OR (\"modified learning convolution algorithm\"))~".
• Removing quotes may allow a broader search: (( modified network estimation algorithm ) OR ( modified learning convolution algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified network estimation algorithm") OR ("modified learning convolution algorithm"))*.
