Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
allocation algorithms » estimation algorithms, approximation algorithms
risk optimization » robust optimization, _ optimization, game optimization
modified risk » modified bi1

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: (( modified risk optimization algorithms ) OR ( modified objective allocation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified risk optimization algorithms ) or ( modified objective allocation algorithms ))*.
