Perhaps you should try some spelling variations:
optimization algorithm » optimization algorithms, optimisation algorithm, estimation algorithm
search algorithm » source algorithm
bi1 optimization » _ optimization, qoe optimization, game optimization
using search » using egarch, nursing research, using servo
modified bi1 » modified _
code » core

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: "(( code using search algorithm ) OR ( modified bi1 optimization algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( code using search algorithm ) OR ( modified bi1 optimization algorithm ))*.
