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

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: (( machine learning solution algorithm ) OR ( modified adaptive optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( machine learning solution algorithm ) or ( modified adaptive optimisation algorithm ))*.
