Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithm, optimized algorithms
estimation algorithms » estimation algorithm, optimisation algorithm, approximation algorithms
policy optimization » topology optimization
posts estimation » pose estimation, pulses estimation, risk estimation

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( policy optimization algorithms ) or ( posts estimation algorithms ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( policy optimization algorithms ) OR ( posts estimation algorithms ))*.
