Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
method algorithm » mom algorithm
qoe optimisation » qoe optimization, _ optimisation, game optimization
using method » nursing methods, focusing method, using metal
modified qoe » modified male, modified _, modified bi1
code » core

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( code using method algorithm ) OR ( modified qoe optimisation algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( code using method algorithm ) OR ( modified qoe optimisation algorithm ))*.
