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 invasive evolution algorithms" » "modified invasive evolution algorithm", "modified invasive convolution algorithms", "modified invasive solution algorithm", "modified invasive ventilation algorithms", "modified passive evolution algorithms"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified invasive evolution algorithms") OR ("modified learning convolution algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified invasive evolution algorithms\") OR (\"modified learning convolution algorithm\"))".
• Removing quotes may allow a broader search: (( modified invasive evolution algorithms ) OR ( modified learning convolution algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified invasive evolution algorithms") OR ("modified learning convolution algorithm"))*.
