Perhaps you should try some spelling variations:
optimization algorithm » optimization algorithms, estimation algorithm, estimation algorithms
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
static optimization » stage optimization, stochastic optimization, staffing optimization
qoe optimisation » qoe optimization, _ optimisation, game optimization
modified qoe » modified male, modified _, modified bi1

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 static optimization algorithm ) OR ( modified qoe optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified static optimization algorithm ) or ( modified qoe optimisation algorithm ))*.
