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

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 bi1 optimization algorithms ) OR ( modified parameter optimisation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified bi1 optimization algorithms ) or ( modified parameter optimisation algorithms ))*.
