Perhaps you should try some spelling variations:
evolutionary algorithm » evolution algorithm, solution algorithm
optimization algorithm » optimization algorithms, optimisation algorithm, estimation algorithm
adaptive evolutionary » objective evolutionary
modified adaptive » modified passive
qoe optimization » game optimization, _ optimization, stage 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 qoe optimization algorithm ) OR ( modified adaptive evolutionary algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified qoe optimization algorithm ) or ( modified adaptive evolutionary algorithm ))*.
