Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
modified control » mode control
method algorithm » mom algorithm
bi1 optimisation » _ optimisation, _ optimization, qoe optimization
control method » control methods
modified bi1 » modified _

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: "(( modified control method algorithm ) OR ( modified bi1 optimisation algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( modified control method algorithm ) OR ( modified bi1 optimisation algorithm ))*.
