Perhaps you should try some spelling variations:
activation algorithm » estimation algorithm, estimation algorithms, optimisation algorithm
evolution algorithm » solution algorithm, evolutionary algorithm, convolution algorithms
thermal activation » chemical activation, thermal oxidation
learning evolution » learning convolution, learning emotion
mobile learning » machine learning

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( modified thermal activation algorithm ) or ( mobile learning evolution algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( modified thermal activation algorithm ) OR ( mobile learning evolution algorithm )).
• Adding a wildcard symbol may retrieve word variants: (( modified thermal activation algorithm ) or ( mobile learning evolution algorithm ))*.
