Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
static optimization » stage optimization, stochastic optimization, staffing optimization
device simulation » via simulation
policy simulation » plant simulation

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: (( static optimization algorithms ) OR ( ((device simulation) OR (policy simulation)) algorithm ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( static optimization algorithms ) or ( ((device simulation) OR (policy simulation)) algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( static optimization algorithms ) or ( ((device simulation) OR (policy simulation)) algorithm ))*.
