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.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified learning convolution algorithm") OR ("modified invasive evolution algorithms"))~.
• Removing quotes may allow a broader search: (( modified learning convolution algorithm ) or ( modified invasive evolution algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified learning convolution algorithm") or ("modified invasive evolution algorithms"))*.
