Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
network optimisation » network optimization
using real » using metal
using raw » using a, using low, using rbf
code » core
certified » verified

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 raw) OR (using real)) algorithm ) OR ( certified network optimisation algorithm ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( code ((using raw) OR (using real)) algorithm ) or ( certified network optimisation algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( code ((using raw) OR (using real)) algorithm ) or ( certified network optimisation algorithm ))*.
