Perhaps you should try some spelling variations:
optimization algorithmss » optimization algorithms, estimation algorithms, estimation algorithm
objective optimisation » objective optimization, multiobjective optimization
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
quantile optimization » quantile estimation, quadratic optimization, static optimization
modified quantile » 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 objective optimisation algorithm ) OR ( modified quantile optimization algorithmss ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified objective optimisation algorithm ) or ( modified quantile optimization algorithmss ))*.
