Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
optimization algorithm » optimisation algorithm, estimation algorithm, estimation algorithms
notion optimization » network optimization, policy optimization, allocation optimization
bi1 optimization » _ optimization, qoe optimization, game optimization
modified bi1 » modified _

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( modified notion optimization algorithms ) or ( modified bi1 optimization algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( modified notion optimization algorithms ) OR ( modified bi1 optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (( modified notion optimization algorithms ) or ( modified bi1 optimization algorithm ))*.
