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