Perhaps you should try some spelling variations:
optimization algorithm » optimization algorithms, optimisation algorithm, estimation algorithm
one approximation » time approximation, _ approximation, rough approximations
adam optimization » game optimization, stage optimization, _ optimization
modified adam » modified df, modified near
modified one » modified male, modified near, modified orca

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: (( modified one approximation algorithms ) OR ( modified adam optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified one approximation algorithms ) or ( modified adam optimization algorithm ))*.
