Perhaps you should try some spelling variations:
simulation algorithms » estimation algorithms, optimization algorithms, estimation algorithm
policy optimization » topology optimization
post optimization » robust optimization, qoe optimization, smooth 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) OR (policy optimization)) algorithms ) or ( device simulation algorithms ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( ((post optimization) OR (policy optimization)) algorithms ) OR ( device simulation algorithms )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((post optimization) OR (policy optimization)) algorithms ) or ( device simulation algorithms ))".
• Adding a wildcard symbol may retrieve word variants: (( ((post optimization) OR (policy optimization)) algorithms ) or ( device simulation algorithms ))*.
