Perhaps you should try some spelling variations:
optimization algorithm » optimization algorithms, optimisation algorithm, estimation algorithm
optimized algorithm » optimized algorithms, optimizer algorithms
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.

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