Perhaps you should try some spelling variations:
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
evolution algorithm » solution algorithm, evolutionary algorithm, convolution algorithms
network estimation » network optimization
modified charging » modified caging, modified carbon
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 ( modified charging evolution algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( designed network estimation algorithms ) OR ( modified charging evolution algorithm )).
• Adding a wildcard symbol may retrieve word variants: (( designed network estimation algorithms ) or ( modified charging evolution algorithm ))*.
