Perhaps you should try some spelling variations:
evolutionary algorithm » evolution algorithm, solution algorithm
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
qoe optimisation » qoe optimization, _ optimisation, game optimization
modified qoe » modified male, modified bi1, modified df

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: "(( modified _ evolutionary algorithm ) OR ( modified qoe optimisation algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( modified _ evolutionary algorithm ) OR ( modified qoe optimisation algorithm ))*.
