Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
objective optimization » multiobjective optimization
optimization algorithm » optimization algorithms, estimation algorithm, estimation algorithms
risk optimisation » _ optimisation, risk estimation
modified risk » modified bi1

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 risk optimisation algorithm ) OR ( modified objective optimization algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( modified risk optimisation algorithm ) OR ( modified objective optimization algorithm ))*.
