Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
network optimisation » network optimization
optimized algorithm » optimized algorithms, optimizer algorithms
df optimized » _ optimized, _ optimize
modified df » modified _, modified adam, modified bi1
defined » designed

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (( defined network optimisation algorithm ) OR ( modified df optimized algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( defined network optimisation algorithm ) or ( modified df optimized algorithm ))*.
