Perhaps you should try some spelling variations:
optimization algorithm » optimization algorithms, optimisation algorithm, estimation algorithm
method algorithm » mom algorithm
bi1 optimization » _ optimization, qoe optimization, game optimization
modified bi1 » modified _
core using » care nursing

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (( ((core using) OR (code using)) method algorithm ) OR ( modified bi1 optimization algorithm ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((core using) OR (code using)) method algorithm ) or ( modified bi1 optimization algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( ((core using) OR (code using)) method algorithm ) or ( modified bi1 optimization algorithm ))*.
