Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
simulation algorithms » estimation algorithms, estimation algorithm, solution algorithm
post optimization » robust optimization, qoe optimization, policy optimization
device simulation » policy simulation, via simulation

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (( post optimization algorithms ) or ( device simulation algorithms ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( post optimization algorithms ) OR ( device simulation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (( post optimization algorithms ) or ( device simulation algorithms ))*.
