Perhaps you should try some spelling variations:
modified learning » mobile learning, modified caging
one approximation » time approximation, _ approximation, rough approximations
video algorithm » vision algorithms, driven algorithm, winner algorithm
learning video » learning aided, learning model, learning via
modified one » modified male, modified near, modified orca

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 video algorithm ) OR ( modified one approximation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified learning video algorithm ) or ( modified one approximation algorithms ))*.
