Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
optimizer algorithms » optimized algorithms, optimized algorithm, optimization algorithms
modified quantile » modified adaptive
modified passive » modified adaptive

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( modified passive optimisation algorithm ) OR ( modified quantile optimizer algorithms ))~".
• Adding a wildcard symbol may retrieve word variants: (( modified passive optimisation algorithm ) OR ( modified quantile optimizer algorithms ))*.
