Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
estimation algorithmss » estimation algorithms, estimation algorithm
static optimization » stage optimization, stochastic optimization, staffing optimization
passive estimation » pose estimation
modified passive » modified adaptive

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 static optimization algorithms ) OR ( modified passive estimation algorithmss ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified static optimization algorithms ) or ( modified passive estimation algorithmss ))*.
