Perhaps you should try some spelling variations:
optimisation algorithms » optimization algorithms, estimation algorithms, estimation algorithm
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
response optimisation » response optimization
risk optimisation » _ optimisation, risk estimation

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