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

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

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