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

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( modified bayesian estimation algorithms ) OR ( mobile learning solution algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( modified bayesian estimation algorithms ) OR ( mobile learning solution algorithm ))*.
