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

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( write estimation algorithms ) OR ( same ((optimizer algorithms) OR (optimized algorithms)) ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( write estimation algorithms ) OR ( same ((optimizer algorithms) OR (optimized algorithms)) ))*".
