Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
optimizer algorithms » optimized algorithms, optimized algorithm, optimization algorithms
parameter optimizer » parameter optimization
qoe optimisation » qoe optimization, _ optimisation, game optimization
core » more, care

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( (code OR core) qoe optimisation algorithm ) or ( modified parameter optimizer algorithms ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( (code OR core) qoe optimisation algorithm ) OR ( modified parameter optimizer algorithms )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( (code OR core) qoe optimisation algorithm ) or ( modified parameter optimizer algorithms ))".
• Adding a wildcard symbol may retrieve word variants: (( (code OR core) qoe optimisation algorithm ) or ( modified parameter optimizer algorithms ))*.
