Perhaps you should try some spelling variations:
optimization algorithmssss » optimization algorithms, optimisation algorithm
adaptive optimization » objective optimization, adaptive quantization, static optimization
allocation estimation » allocation optimization, motion estimation
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
modified adaptive » modified passive

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( modified adaptive optimization algorithmssss ) or ( modified allocation estimation algorithms ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( modified adaptive optimization algorithmssss ) OR ( modified allocation estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (( modified adaptive optimization algorithmssss ) or ( modified allocation estimation algorithms ))*.
