Perhaps you should try some spelling variations:
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
network estimation » network optimization
solution algorithm » evolution algorithm, convolution algorithms, evolutionary algorithm
defined » designed
discursive » dispersive

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( defined network estimation algorithms ) OR ( modified discursive solution algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( defined network estimation algorithms ) OR ( modified discursive solution algorithm ))*.
