Perhaps you should try some spelling variations:
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
optimized algorithms » optimizer algorithms, optimization algorithms
optimized algorithm » optimizer algorithms
write estimation » risk estimation, pose estimation
pulses » pulse, pulsed

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

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