Perhaps you should try some spelling variations:
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
predation algorithm » predators algorithm, estimation algorithm
network estimation » network optimization
learning predation » learning prediction, learning emotion
designed network » defined network

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( designed network estimation algorithms ) or ( machine learning predation algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( designed network estimation algorithms ) OR ( machine learning predation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (( designed network estimation algorithms ) or ( machine learning predation algorithm ))*.
