Perhaps you should try some spelling variations:
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
objective estimation » objective optimization, objective allocation
optimized algorithm » optimized algorithms, optimizer algorithms
network optimized » network optimization
verified network » certified 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: (( modified objective estimation algorithms ) or ( verified network optimized algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( modified objective estimation algorithms ) OR ( verified network optimized algorithm )).
• Adding a wildcard symbol may retrieve word variants: (( modified objective estimation algorithms ) or ( verified network optimized algorithm ))*.
