Perhaps you should try some spelling variations:
convolution algorithm » convolution algorithms, evolution algorithm, solution algorithm
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
modified learning » mobile learning, modified caging
carbon estimation » motion estimation

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 carbon estimation algorithms ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( modified learning convolution algorithm ) OR ( modified carbon estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (( modified learning convolution algorithm ) or ( modified carbon estimation algorithms ))*.
