Perhaps you should try some spelling variations:
optimization algorithm » optimization algorithms, optimisation algorithm, estimation algorithm
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
static optimization » stage optimization, stochastic optimization, staffing optimization
robust estimation » robust optimization, pose estimation, risk estimation

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