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

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 ( write ((optimizer algorithms) or (optimized algorithm)) ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( post optimization algorithms ) OR ( write ((optimizer algorithms) OR (optimized algorithm)) )).
• Adding a wildcard symbol may retrieve word variants: (( post optimization algorithms ) or ( write ((optimizer algorithms) or (optimized algorithm)) ))*.
