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 algorithms" » "modified network estimation algorithm", "modified network optimization algorithms", "modified network optimisation algorithm", "certified network estimation algorithms", "defined network estimation algorithms", "modified near estimation algorithms"

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