Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
pulses estimation » pose estimation
risk optimization » robust optimization, _ optimization, game optimization
poses estimation » pose estimation, cover estimations, 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: (( ((poses estimation) OR (pulses estimation)) algorithm ) or ( risk optimization algorithms ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( ((poses estimation) OR (pulses estimation)) algorithm ) OR ( risk optimization algorithms )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((poses estimation) OR (pulses estimation)) algorithm ) or ( risk optimization algorithms ))".
• Adding a wildcard symbol may retrieve word variants: (( ((poses estimation) OR (pulses estimation)) algorithm ) or ( risk optimization algorithms ))*.
