Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
source algorithm » our algorithm, search algorithm
bi1 optimisation » _ optimisation, _ optimization, qoe optimization
using source » using force, using morse
modified bi1 » modified _
code » core

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: (( code using source algorithm ) OR ( modified bi1 optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( code using source algorithm ) or ( modified bi1 optimisation algorithm ))*.
