Perhaps you should try some spelling variations:
optimization algorithms » estimation algorithms, estimation algorithm, optimizer algorithms
optimisation algorithm » estimation algorithm, estimation algorithms
optimized algorithms » optimized algorithm, optimizer algorithms
post optimisation » robust optimization, _ optimisation, qoe optimization

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( pose ((optimization algorithms) OR (optimized algorithms)) ) or ( post optimisation algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( pose ((optimization algorithms) OR (optimized algorithms)) ) OR ( post optimisation algorithm )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( pose ((optimization algorithms) OR (optimized algorithms)) ) or ( post optimisation algorithm ))".
• Adding a wildcard symbol may retrieve word variants: (( pose ((optimization algorithms) OR (optimized algorithms)) ) or ( post optimisation algorithm ))*.
