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

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( modified bi1 evolution algorithm ) OR ( modified qoe optimization algorithm ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( modified bi1 evolution algorithm ) OR ( modified qoe optimization algorithm ))".
• Adding a wildcard symbol may retrieve word variants: (( modified bi1 evolution algorithm ) OR ( modified qoe optimization algorithm ))*.
