Perhaps you should try some spelling variations:
quantization algorithm » estimation algorithm
adaptive quantization » adaptive ventilation
simulation algorithm » estimation algorithm, solution algorithm, optimisation algorithm
modified adaptive » modified passive
3d simulation » _ simulation, a simulation, mri simulation
modified 3d » modified _, modified df, modified adam

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 adaptive quantization algorithm ) OR ( modified 3d simulation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified adaptive quantization algorithm ) or ( modified 3d simulation algorithm ))*.
