Perhaps you should try some spelling variations:
optimization algorithmss » optimisation algorithm, estimation algorithms, estimation algorithm
parameters optimization » parameter optimization, parameter estimation
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
cover optimization » qoe optimization, game optimization

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: "(( cover optimization algorithmss ) OR ( parameters optimization algorithms ))~".
• Adding a wildcard symbol may retrieve word variants: (( cover optimization algorithmss ) OR ( parameters optimization algorithms ))*.
