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 passive » modified adaptive
modified network » certified network, defined network, modified near

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: "(( modified passive evolution algorithm ) OR ( modified network estimation algorithms ))~".
• Adding a wildcard symbol may retrieve word variants: (( modified passive evolution algorithm ) OR ( modified network estimation algorithms ))*.
