Perhaps you should try some spelling variations:
optimization algorithm » optimization algorithms, optimisation algorithm, estimation algorithm
qoe optimization » game optimization, _ optimization, stage optimization
mental algorithm » genetic algorithm, control algorithm, mppt algorithm
using mental » using metal, nursing mental, using medical
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: (( (code OR core) using mental algorithm ) OR ( modified qoe optimization algorithm ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( (code OR core) using mental algorithm ) or ( modified qoe optimization algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( (code OR core) using mental algorithm ) or ( modified qoe optimization algorithm ))*.
