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

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( code using method algorithm ) or ( modified bi1 optimization algorithms ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( code using method algorithm ) OR ( modified bi1 optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (( code using method algorithm ) or ( modified bi1 optimization algorithms ))*.
