Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
approximation algorithm » approximation algorithms
adaptive optimization » objective optimization, adaptive quantization, static optimization
seird approximation » time approximation, network approximation
modified adaptive » modified passive
modified seird » 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 adaptive optimization algorithms ) OR ( modified seird approximation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified adaptive optimization algorithms ) or ( modified seird approximation algorithm ))*.
