Perhaps you should try some spelling variations:
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
simulation algorithm » estimation algorithm, solution algorithm, optimisation algorithm
static estimation » static optimization
device simulation » policy simulation, via 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 estimation algorithms ) OR ( device simulation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( static estimation algorithms ) or ( device simulation algorithm ))*.
