Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
static optimization » stage optimization, stochastic optimization, staffing optimization
parameter estimates » parameter estimation
estimates algorithm » estimation algorithm, estimation algorithms

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