Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
optimization algorithm » optimisation algorithm, estimation algorithm, estimation algorithms
bi1 optimization » _ optimization, qoe optimization, game optimization
modified bi1 » modified _
allocation » location

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 optimization algorithm ) or ( modified allocation optimization algorithms ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( modified bi1 optimization algorithm ) OR ( modified allocation optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (( modified bi1 optimization algorithm ) or ( modified allocation optimization algorithms ))*.
