Perhaps you should try some spelling variations:
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
allocation estimation » allocation optimization, motion estimation
optimizer algorithms » optimized algorithms, optimized algorithm, optimization algorithms
df optimizer » _ optimized, _ optimize
modified df » modified _, modified adam, modified bi1

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 df optimizer algorithms ) OR ( modified allocation estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified df optimizer algorithms ) or ( modified allocation estimation algorithms ))*.
