Perhaps you should try some spelling variations:
evolution algorithm » evolutionary algorithm, convolution algorithms, estimation algorithm
parameter estimates » parameter estimation
estimates algorithm » estimation algorithm, estimation algorithms
solution algorithm » convolution algorithms, evolutionary algorithm, estimation algorithm

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

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