Perhaps you should try some spelling variations:
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
optimized algorithms » optimized algorithm, optimizer algorithms, optimization algorithms
objective optimized » objective optimal, objective optimization
nodal estimation » pose estimation
modified nodal » modified adam, modified near

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (( modified nodal estimation algorithms ) OR ( modified objective optimized algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified nodal estimation algorithms ) or ( modified objective optimized algorithms ))*.
