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

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 solution algorithm ) OR ( modified static estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified learning solution algorithm ) or ( modified static estimation algorithms ))*.
